Description
CONJUGATED POLYMERS AND THEIRUSE IN OPTOELECTRONIC
DEVICES
Cross Reference to Related Applications
[0001] This application claims priority to and the benefit of U.S. Provisional Patent Application Serial No. 61/180,256, filed on May 21, 2009, and U.S. Provisional Patent Application Serial No. 61/323,152, filed on April 12, 2010, the disclosure of each of which is incorporated by reference herein in its entirety.
Background
[0002] A new generation of optoelectronic devices such as organic photovoltaics (OPVs) and organic light-emitting transistors (OLETs) are fabricated using organic semiconductors as their active components. To be commercially relevant, these organic semiconductor-based devices should be processable in a cost-effective manner.
[0003] Bulk heterojunction (BHJ) solar cells commonly are considered the most promising OPV structures because they can be fabricated using roll-to-roll and large-scale production. BHJ solar cells include a photoactive layer disposed between an anode and a cathode, where the photoactive layer is composed of a blend film including a "donor" material and an "acceptor" material. Figure 1 illustrates a representative BHJ organic solar cell structure.
[0004] State-of-the-art BHJ solar cells use fullerene-based compounds as the acceptor material. Typical fullerenes include C60 or C70 "bucky ball" compounds functionalized with solubilizing side chains, such as C60 [6,6]-phenyl-C61 -butyric acid methyl ester (CβoPCBM) or C70PCBM. The most common donor material used in BHJ solar cells is poly(3-hexylthiophene) (P3HT). However, P3HT/PCBM-based solar cells have several fundamental limitations. For example, the band-gap of P3HT is ~ 2.0 eV, and it can absorb only a small portion (30%) of the solar spectrum.
[0005] Accordingly, the art desires new organic semiconductor materials for use in optoelectronic devices such as organic photovoltaics.
Summary
[0006] In light of the foregoing, the present teachings provide certain oligomeric and polymeric compounds that can be used as organic semiconductors. Also provided are associated devices and related methods for the preparation and use of these compounds.
[0007] The present compounds can exhibit properties such as excellent charge transport characteristics in ambient conditions, optimized optical absorption, chemical stability, low-temperature processability, large solubility in common solvents, and processing versatility (e.g., via various solution processes). As a result, optoelectronic devices such as solar cells that incorporate one or more of the present compounds as a photoactive layer can exhibit high performance in ambient conditions, for example, demonstrating one or more of low band-gap, high fill factor, high open circuit voltage, and high power conversion efficiency, and preferably all of these criteria. Similarly, other organic semiconductor-based devices such as OLETs can be fabricated efficiently using the organic semiconductor materials described herein.
[0008] The present teachings also provide methods of preparing such compounds and semiconductor materials, as well as various compositions, composites, and devices that incorporate the compounds and semiconductor materials disclosed herein.
[0009] The foregoing as well as other features and advantages of the present teachings will be more fully understood from the following figures, description, examples, and claims.
Brief Description of Drawings
[0010] It should be understood that the drawings described below are for illustration purpose only. The drawings are not necessarily to scale, with emphasis generally being placed upon illustrating the principles of the present teachings. The drawings are not intended to limit the scope of the present teachings in any way.
[0011] Figure 1 illustrates a representative bulk-heterojunction (BHJ) organic photovoltaic device (also known as a solar cell) structure, which can incorporate one or more compounds of the present teachings as its photoactive layer (as donor and/or acceptor materials).
Detailed Description
[0012] The present teachings provide organic semiconductor materials that are prepared from various π-conjugated oligomeric and polymeric compounds having typically an electron-rich repeat unit and an electron-poor repeat unit. Compounds of the present teachings can exhibit semiconductor behavior such as high carrier mobility and/or good current modulation characteristics in a field-effect device, optimized light
absorption/charge separation in a photovoltaic device, and/or charge transport/recombination/light emission in a light-emitting device. In addition, the present compounds can possess certain processing advantages such as solution-processability and/or good stability (e.g., air stability) in ambient conditions. The compounds of the present teachings can be used to prepare either p-type (donor or hole-transporting), n-type (acceptor or electron-transporting), or ambipolar semiconductor materials, which in turn can be used to fabricate various organic or hybrid optoelectronic articles, structures and devices, including organic photovoltaic devices and organic light-emitting transistors.
[0013] Throughout the application, where compositions are described as having, including, or comprising specific components, or where processes are described as having, including, or comprising specific process steps, it is contemplated that compositions of the present teachings also consist essentially of, or consist of, the recited components, and that the processes of the present teachings also consist essentially of, or consist of, the recited process steps.
[0014] In the application, where an element or component is said to be included in and/or selected from a list of recited elements or components, it should be understood that the element or component can be any one of the recited elements or components, or the element or component can be selected from a group consisting of two or more of the recited elements or components. Further, it should be understood that elements and/or features of a composition, an apparatus, or a method described herein can be combined in a variety of ways without departing from the spirit and scope of the present teachings, whether explicit or implicit herein.
[0015] The use of the terms "include," "includes", "including," "have," "has," or "having" should be generally understood as open-ended and non-limiting unless specifically stated otherwise.
[0016] The use of the singular herein includes the plural (and vice versa) unless specifically stated otherwise. In addition, where the use of the term "about" is before a quantitative value, the present teachings also include the specific quantitative value itself, unless specifically stated otherwise. As used herein, the term "about" refers to a ±10% variation from the nominal value unless otherwise indicated or inferred.
[0017] It should be understood that the order of steps or order for performing certain actions is immaterial so long as the present teachings remain operable. Moreover, two or more steps or actions may be conducted simultaneously.
[0018] As used herein, an "oligomeric compound" (or "oligomer") or a "polymeric compound" (or "polymer") refers to a molecule including a plurality of one or more repeat units connected by covalent chemical bonds. An oligomeric or polymeric compound can be represented by the general formula:
-H- wherein M is the repeat unit or monomer. The degree of polymerization can range from 2 to greater than 10,000. For example, for oligomeric compounds, the degree of polymerization can range from 2 to 9; and for polymeric compounds, the degree of polymerization can range from 10 to about 10,000. The oligomeric or polymeric compound can have only one type of repeat unit as well as two or more types of different repeat units. When a polymeric compound has only one type of repeat unit, it can be referred to as a homopolymer. When a polymeric compound has two or more types of different repeat units, the term "copolymer" or "copolymeric compound" can be used instead. The oligomeric or polymeric compound can be linear or branched. Branched polymers can include dendritic polymers, such as dendronized polymers, hyperbranched polymers, brush polymers (also called bottle-brushes), and the like. Unless specified otherwise, the assembly of the repeat units in the copolymer can be head-to-tail, head-to- head, or tail-to-tail. In addition, unless specified otherwise, the copolymer can be a random copolymer, an alternating copolymer, or a block copolymer. For example, the general formula:
'-(-Ax-B7^*
can be used to represent a co-oligomer or copolymer of A and B having x mole fraction of A and y mole fraction of B in the copolymer, where the manner in which comonomers A and B is repeated can be alternating, random, regiorandom, regioregular, or in blocks. The degree of polymerization (n) can range from 2 to greater than 10,000.
[0019] As used herein, a "cyclic moiety" can include one or more (e.g., 1-6) carbocyclic or heterocyclic rings. The cyclic moiety can be a cycloalkyl group, a heterocycloalkyl group, an aryl group, or a heteroaryl group (i.e., can include only saturated bonds, or can
include one or more unsaturated bonds regardless of aromaticity), each including, for example, 3-24 ring atoms and optionally can be substituted as described herein. In embodiments where the cyclic moiety is a "monocyclic moiety," the "monocyclic moiety" can include a 3-14 membered aromatic or non-aromatic, carbocyclic or heterocyclic ring. A monocyclic moiety can include, for example, a phenyl group or a 5- or 6-membered heteroaryl group, each of which optionally can be substituted as described herein. In embodiments where the cyclic moiety is a "polycyclic moiety," the "polycyclic moiety" can include two or more rings fused to each other (i.e., sharing a common bond) and/or connected to each other via a spiro atom, or one or more bridged atoms. A polycyclic moiety can include an 8-24 membered aromatic or non-aromatic, carbocyclic or heterocyclic ring, such as a Cg-24 aryl group or an 8-24 membered heteroaryl group, each of which optionally can be substituted as described herein.

In various embodiments, an alkyl group can have 1 to 40 carbon atoms (i.e., Ci_4o alkyl group), for example, 1-20 carbon atoms (i.e., Ci_2o alkyl group). In some embodiments, an alkyl group can have 1 to 6 carbon atoms, and can be referred to as a "lower alkyl group." Examples of lower alkyl groups include methyl, ethyl, propyl (e.g., n-propyl and iso- propyl), and butyl groups (e.g., n-butyl, ώo-butyl, sec-butyl, tert-bvΛy\). In some embodiments, alkyl groups can be substituted as described herein. An alkyl group is generally not substituted with another alkyl group, an alkenyl group, or an alkynyl group.

butyne). In various embodiments, an alkynyl group can have 2 to 40 carbon atoms (i.e., C2-40 alkynyl group), for example, 2 to 20 carbon atoms (i.e., C2-20 alkynyl group). In some embodiments, alkynyl groups can be substituted as described herein. An alkynyl group is generally not substituted with another alkynyl group, an alkyl group, or an alkenyl group.
[0029] As used herein, "cycloalkyl" refers to a non-aromatic carbocyclic group including cyclized alkyl, alkenyl, and alkynyl groups. In various embodiments, a cycloalkyl group can have 3 to 24 carbon atoms, for example, 3 to 20 carbon atoms (e.g., C3_i4 cycloalkyl group). A cycloalkyl group can be monocyclic (e.g., cyclohexyl) or polycyclic (e.g., containing fused, bridged, and/or spiro ring systems), where the carbon atoms are located inside or outside of the ring system. Any suitable ring position of the cycloalkyl group can be covalently linked to the defined chemical structure. Examples of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclopentenyl, cyclohexenyl, cyclohexadienyl, cycloheptatrienyl, norbornyl, norpinyl, norcaryl, adamantyl, and spiro[4.5]decanyl groups, as well as their homologs, isomers, and the like. In some embodiments, cycloalkyl groups can be substituted as described herein.
[0030] As used herein, "heteroatom" refers to an atom of any element other than carbon or hydrogen and includes, for example, nitrogen, oxygen, silicon, sulfur, phosphorus, and selenium.
[0031] As used herein, "cycloheteroalkyl" refers to a non-aromatic cycloalkyl group that contains at least one ring heteroatom selected from O, S, Se, N, P, and Si (e.g., O, S, and N), and optionally contains one or more double or triple bonds. A cycloheteroalkyl group can have 3 to 24 ring atoms, for example, 3 to 20 ring atoms (e.g., 3-14 membered cycloheteroalkyl group). One or more N, P, S, or Se atoms (e.g., N or S) in a cycloheteroalkyl ring may be oxidized (e.g., morpholine N-oxide, thiomorpholine S- oxide, thiomorpholine S,S-dioxide). In some embodiments, nitrogen or phosphorus atoms of cycloheteroalkyl groups can bear a substituent, for example, a hydrogen atom, an alkyl group, or other substituents as described herein. Cycloheteroalkyl groups can also contain one or more oxo groups, such as oxopiperidyl, oxooxazolidyl, dioxo- (lH,3H)-pyrimidyl, oxo-2(lH)-pyridyl, and the like. Examples of cycloheteroalkyl groups include, among others, morpholinyl, thiomorpholinyl, pyranyl, imidazolidinyl, imidazolinyl, oxazolidinyl, pyrazolidinyl, pyrazolinyl, pyrrolidinyl, pyrrolinyl,

[0032] As used herein, "aryl" refers to an aromatic monocyclic hydrocarbon ring system or a polycyclic ring system in which two or more aromatic hydrocarbon rings are fused (i.e., having a bond in common with) together or at least one aromatic monocyclic hydrocarbon ring is fused to one or more cycloalkyl and/or cycloheteroalkyl rings. An aryl group can have 6 to 24 carbon atoms in its ring system (e.g., C6-20 aryl group), which can include multiple fused rings. In some embodiments, a polycyclic aryl group can have 8 to 24 carbon atoms. Any suitable ring position of the aryl group can be covalently linked to the defined chemical structure. Examples of aryl groups having only aromatic carbocyclic ring(s) include phenyl, 1-naphthyl (bicyclic), 2-naphthyl (bicyclic), anthracenyl (tricyclic), phenanthrenyl (tricyclic), pentacenyl (pentacyclic), and like groups. Examples of polycyclic ring systems in which at least one aromatic carbocyclic ring is fused to one or more cycloalkyl and/or cycloheteroalkyl rings include, among others, benzo derivatives of cyclopentane (i.e., an indanyl group, which is a 5,6-bicyclic cycloalkyl/aromatic ring system), cyclohexane (i.e., a tetrahydronaphthyl group, which is a 6,6-bicyclic cycloalkyl/aromatic ring system), imidazoline (i.e., a benzimidazolinyl group, which is a 5,6-bicyclic cycloheteroalkyl/aromatic ring system), and pyran (i.e., a chromenyl group, which is a 6,6-bicyclic cycloheteroalkyl/aromatic ring system). Other examples of aryl groups include benzodioxanyl, benzodioxolyl, chromanyl, indolinyl groups, and the like. In some embodiments, aryl groups can be substituted as described herein. In some embodiments, an aryl group can have one or more halogen substituents, and can be referred to as a "haloaryl" group. Perhaloaryl groups, i.e., aryl groups where all of the hydrogen atoms are replaced with halogen atoms (e.g., -C6Fs), are included within the definition of "haloaryl." In certain embodiments, an aryl group is substituted with another aryl group and can be referred to as a biaryl group. Each of the aryl groups in the biaryl group can be substituted as disclosed herein.
[0033] As used herein, "heteroaryl" refers to an aromatic monocyclic ring system containing at least one ring heteroatom selected from oxygen (O), nitrogen (N), sulfur (S), silicon (Si), and selenium (Se) or a polycyclic ring system where at least one of the rings present in the ring system is aromatic and contains at least one ring heteroatom. Polycyclic heteroaryl groups include those having two or more heteroaryl rings fused together, as well as those having at least one monocyclic heteroaryl ring fused to one or
more aromatic carbocyclic rings, non-aromatic carbocyclic rings, and/or non-aromatic cycloheteroalkyl rings. A heteroaryl group, as a whole, can have, for example, 5 to 24 ring atoms and contain 1-5 ring heteroatoms (i.e., 5-20 membered heteroaryl group). The heteroaryl group can be attached to the defined chemical structure at any heteroatom or carbon atom that results in a stable structure. Generally, heteroaryl rings do not contain O-O, S-S, or S-O bonds. However, one or more N or S atoms in a heteroaryl group can be oxidized (e.g., pyridine N-oxide, thiophene S-oxide, thiophene S,S-dioxide). Examples of heteroaryl groups include, for example, the 5- or 6-membered monocyclic and 5-6 bicyclic ring systems shown below:
where T is O, S, NH, N-alkyl, N-aryl, N-(arylalkyl) (e.g., N-benzyl), SiH2, SiH(alkyl), Si(alkyl)2, SiH(arylalkyl), Si(arylalkyl)2, or Si(alkyl)(arylalkyl). Examples of such heteroaryl rings include pyrrolyl, furyl, thienyl, pyridyl, pyrimidyl, pyridazinyl, pyrazinyl, triazolyl, tetrazolyl, pyrazolyl, imidazolyl, isothiazolyl, thiazolyl, thiadiazolyl, isoxazolyl, oxazolyl, oxadiazolyl, indolyl, isoindolyl, benzofuryl, benzothienyl, quinolyl, 2- methylquinolyl, isoquinolyl, quinoxalyl, quinazolyl, benzotriazolyl, benzimidazolyl, benzothiazolyl, benzisothiazolyl, benzisoxazolyl, benzoxadiazolyl, benzoxazolyl, cinnolinyl, lH-indazolyl, 2H-indazolyl, indolizinyl, isobenzofuyl, naphthyridinyl, phthalazinyl, pteridinyl, purinyl, oxazolopyridinyl, thiazolopyridinyl, imidazopyridinyl, furopyridinyl, thienopyridinyl, pyridopyrimidinyl, pyridopyrazinyl, pyridopyridazinyl, thienothiazolyl, thienoxazolyl, thienoimidazolyl groups, and the like. Further examples of heteroaryl groups include 4,5,6,7-tetrahydroindolyl, tetrahydroquinolinyl,
benzothienopyridinyl, benzofuropyridinyl groups, and the like. In some embodiments, heteroaryl groups can be substituted as described herein.
[0034] Compounds of the present teachings can include a "divalent group" defined herein as a linking group capable of forming a covalent bond with two other moieties. For example, compounds of the present teachings can include a divalent Ci_2o alkyl group (e.g., a methylene group), a divalent C2-20 alkenyl group (e.g., a vinylyl group), a divalent C2-20 alkynyl group (e.g., an ethynylyl group), a divalent C6-14 aryl group (e.g., a phenylyl group); a divalent 3-14 membered cycloheteroalkyl group (e.g., a pyrrolidylyl), and/or a divalent 5-14 membered heteroaryl group (e.g., a thienylyl group). Generally, a chemical group (e.g., -Ar-) is understood to be divalent by the inclusion of the two bonds before and after the group.
[0035] The electron-donating or electron-withdrawing properties of several hundred of the most common substituents, reflecting all common classes of substituents have been determined, quantified, and published. The most common quantification of electron- donating and electron- withdrawing properties is in terms of Hammett σ values. Hydrogen has a Hammett σ value of zero, while other substituents have Hammett σ values that increase positively or negatively in direct relation to their electron- withdrawing or electron-donating characteristics. Substituents with negative Hammett σ values are considered electron-donating, while those with positive Hammett σ values are considered electron- withdrawing. See Lange's Handbook of Chemistry, 12th ed., McGraw Hill, 1979, Table 3-12, pp. 3-134 to 3-138, which lists Hammett σ values for a large number of commonly encountered substituents and is incorporated by reference herein.
[0036] It should be understood that the term "electron-accepting group" can be used synonymously herein with "electron acceptor" and "electron-withdrawing group". In particular, an "electron-withdrawing group" ("EWG") or an "electron-accepting group" or an "electron-acceptor" refers to a functional group that draws electrons to itself more than a hydrogen atom would if it occupied the same position in a molecule. Examples of electron-withdrawing groups include, but are not limited to, halogen or halo (e.g., F, Cl, Br, I), -NO2, -CN, -NC, -S(R°)2 +, -N(R°)3 +, -SO3H, -SO2R0, -SO3R0, -SO2NHR0, -SO2N(R°)2, -COOH, -COR0, -COOR0, -CONHR0, -C0N(R°)2, C1-40 haloalkyl groups, C6-14 aryl groups, and 5-14 membered electron-poor heteroaryl groups; where R0 is a C1-2Q
alkyl group, a C2-20 alkenyl group, a C2-20 alkynyl group, a Ci_2o haloalkyl group, a Ci_2o alkoxy group, a C6-I4 aryl group, a C3-14 cycloalkyl group, a 3-14 membered cycloheteroalkyl group, and a 5-14 membered heteroaryl group, each of which optionally can be substituted as described herein. For example, each of the Ci_2o alkyl group, the C2- 20 alkenyl group, the C2-20 alkynyl group, the Ci_2o haloalkyl group, the Ci_2o alkoxy group, the C6-14 aryl group, the C3-14 cycloalkyl group, the 3-14 membered cycloheteroalkyl group, and the 5-14 membered heteroaryl group optionally can be substituted with 1-5 small electron- withdrawing groups such as F, Cl, Br, -NO2, -CN, -NC ,-S(R°)2 + ,-N(R°)3 +, -SO3H, -SO2R0, -SO3R0, -SO2NHR0, -SO2N(R°)2, -COOH, -COR0, -COOR0 -CONHR0, and -C0N(R°)2.
[0037] It should be understood that the term "electron-donating group" can be used synonymously herein with "electron donor". In particular, an "electron-donating group" or an "electron-donor" refers to a functional group that donates electrons to a neighboring atom more than a hydrogen atom would if it occupied the same position in a molecule. Examples of electron-donating groups include -OH, -OR0, -NH2, -NHR0, -N(R°)2, and 5-14 membered electron-rich heteroaryl groups, where R0 is a C1-20 alkyl group, a C2-20 alkenyl group, a C2-20 alkynyl group, a C6-14 aryl group, or a C3-14 cycloalkyl group.
[0038] Various unsubstituted heteroaryl groups can be described as electron-rich (or π- excessive) or electron-poor (or π-defϊcient). Such classification is based on the average electron density on each ring atom as compared to that of a carbon atom in benzene. Examples of electron-rich systems include 5-membered heteroaryl groups having one heteroatom such as furan, pyrrole, and thiophene; and their benzofused counterparts such as benzofuran, benzopyrrole, and benzothiophene. Examples of electron-poor systems include 6-membered heteroaryl groups having one or more heteroatoms such as pyridine, pyrazine, pyridazine, and pyrimidine; as well as their benzofused counterparts such as quinoline, isoquinoline, quinoxaline, cinnoline, phthalazine, naphthyridine, quinazoline, phenanthridine, acridine, and purine. Mixed heteroaromatic rings can belong to either class depending on the type, number, and position of the one or more heteroatom(s) in the ring. See Katritzky, A.R and Lagowski, J.M., Heterocyclic Chemistry (John Wiley & Sons, New York, 1960).
[0039] At various places in the present specification, substituents are disclosed in groups or in ranges. It is specifically intended that the description include each and every individual subcombination of the members of such groups and ranges. For example, the
term "Ci_6 alkyl" is specifically intended to individually disclose C1, C2, C3, C4, C5, C6, Ci-C6, C1-C5, C1-C4, C1-C3, C1-C2, C2-C6, C2-C5, C2-C4, C2-C3, C3-C6, C3-C5, C3-C4, C4-C6, C4-C5, and C5-C6 alkyl.

Additional examples include that the phrase "optionally substituted with 1-5 substituents" is specifically intended to individually disclose a chemical group that can include 0, 1, 2, 3, 4, 5, 0-5, 0-4, 0-3, 0-2, 0-1, 1-5, 1-4, 1-3, 1-2, 2-5, 2-4, 2-3, 3-5, 3-4, and 4-5 substituents.
[0040] Compounds described herein can contain an asymmetric atom (also referred as a chiral center) and some of the compounds can contain two or more asymmetric atoms or centers, which can thus give rise to optical isomers (enantiomers) and diastereomers (geometric isomers). The present teachings include such optical isomers and diastereomers, including their respective resolved enantiomerically or diastereomerically pure isomers (e.g., (+) or (-) stereoisomer) and their racemic mixtures, as well as other mixtures of the enantiomers and diastereomers. In some embodiments, optical isomers can be obtained in enantiomerically enriched or pure form by standard procedures known to those skilled in the art, which include, for example, chiral separation, diastereomeric salt formation, kinetic resolution, and asymmetric synthesis. The present teachings also encompass cis- and trans-isomers of compounds containing alkenyl moieties (e.g., alkenes, azo, and imines). It also should be understood that the compounds of the present teachings encompass all possible regioisomers in pure form and mixtures thereof. In some embodiments, the preparation of the present compounds can include separating such isomers using standard separation procedures known to those skilled in the art, for example, by using one or more of column chromatography, thin-layer chromatography, simulated moving-bed chromatography, and high-performance liquid chromatography. However, mixtures of regioisomers can be used similarly to the uses of each individual regioisomer of the present teachings as described herein and/or known by a skilled artisan.
[0041] It is specifically contemplated that the depiction of one regioisomer includes any other regioisomers and any regioisomeric mixtures unless specifically stated otherwise.
[0042] As used herein, a "leaving group" ("LG") refers to a charged or uncharged atom (or group of atoms) that can be displaced as a stable species as a result of, for example, a substitution or elimination reaction. Examples of leaving groups include, but are not limited to, halogen (e.g., Cl, Br, I), azide (N3), thiocyanate (SCN), nitro (NO2), cyanate (CN), water (H2O), ammonia (NH3), and sulfonate groups (e.g., OSO2-R, wherein R can be a C1-10 alkyl group or a C6-I4 aryl group each optionally substituted with 1-4 groups independently selected from a C1-10 alkyl group and an electron- withdrawing group) such as tosylate (toluenesulfonate, OTs), mesylate (methanesulfonate, OMs), brosylate (p-bromobenzenesulfonate, OBs), nosylate (4-nitrobenzenesulfonate, ONs), and triflate (trifluoromethanesulfonate, OTf).
[0043] As used herein, a "p-type semiconductor material" or a "donor" material refers to a semiconductor material having holes as the majority current or charge carriers. In some embodiments, when a p-type semiconductor material is deposited on a substrate, it can provide a hole mobility in excess of about 10~5 cm2/Vs. In the case of field-effect devices, a p-type semiconductor can also exhibit a current on/off ratio of greater than about 10.
[0044] As used herein, an "n-type semiconductor material" or an "acceptor" material refers to a semiconductor material having electrons as the majority current or charge carriers. In some embodiments, when an n-type semiconductor material is deposited on a substrate, it can provide an electron mobility in excess of about 10~5 cm2/Vs. In the case of field-effect devices, an n-type semiconductor can also exhibit a current on/off ratio of greater than about 10.
[0045] As used herein, "mobility" refers to a measure of the velocity with which charge carriers, for example, holes (or units of positive charge) in the case of a p-type semiconductor material and electrons in the case of an n-type semiconductor material, move through the material under the influence of an electric field. This parameter, which depends on the device architecture, can be measured using a field-effect device or space- charge limited current measurements.
[0046] As used herein, fill factor (FF) is the ratio (given as a percentage) of the actual maximum obtainable power, (Pm or Vmp * Jmp), to the theoretical (not actually obtainable) power, (Jsc x Voc). Accordingly, FF can be determined using the equation:
FF = (Vmp * Jmp) / (Jsc * Voc)
where Jmp and Vmp represent the current density and voltage at the maximum power point (Pm), respectively, this point being obtained by varying the resistance in the circuit until J * V is at its greatest value; and Jsc and Voc represent the short circuit current and the open circuit voltage, respectively. Fill factor is a key parameter in evaluating the performance of solar cells. Commercial solar cells typically have a fill factor of about 0.60% or greater.
[0047] As used herein, the open-circuit voltage (Voc) is the difference in the electrical potentials between the anode and the cathode of a device when there is no external load connected.
[0048] As used herein, the power conversion efficiency (PCE) of a solar cell is the percentage of power converted from absorbed light to electrical energy. The PCE of a solar cell can be calculated by dividing the maximum power point (Pm) by the input light irradiance (E, in W/m2) under standard test conditions (STC) and the surface area of the solar cell (Ac in m2). STC typically refers to a temperature of 250C and an irradiance of 1000 W/m2 with an air mass 1.5 (AM 1.5) spectrum.
[0049] As used herein, a component (such as a thin film layer) can be considered "photoactive" if it contains one or more compounds that can absorb photons to produce excitons for the generation of a photocurrent.
[0050] As used herein, a compound can be considered "ambient stable" or "stable at ambient conditions" when a transistor incorporating the compound as its semiconducting material exhibits a carrier mobility that is maintained at about its initial measurement when the compound is exposed to ambient conditions, for example, air, ambient temperature, and humidity, over a period of time. For example, a compound can be described as ambient stable if a transistor incorporating the compound shows a carrier mobility that does not vary more than 20% or more than 10% from its initial value after exposure to ambient conditions, including, air, humidity and temperature, over a 3 day, 5 day, or 10 day period.
[0051] As used herein, "solution-processable" refers to compounds (e.g., polymers), materials, or compositions that can be used in various solution-phase processes including spin-coating, printing (e.g., inkjet printing, screen printing, pad printing, offset printing, gravure printing, flexographic printing, lithographic printing, mass-printing and the like), spray coating, electrospray coating, drop casting, dip coating, and blade coating.
[0052] Throughout the specification, structures may or may not be presented with chemical names. Where any question arises as to nomenclature, the structure prevails.
[0053] The present teachings relate to certain oligomeric and polymeric compounds that can be used as organic semiconductors. The present compounds can have good solubility in various common solvents and good stability in air. When incorporated into optical or optoelectronic devices including, but not limited to, photovoltaic or solar cells, light emitting diodes, and light emitting transistors, the present compounds can confer various desirable performance properties. For example, when the present compounds are used in a photoactive layer of a solar cell (e.g., bulk heterojunction devices), the solar cell can exhibit a power conversion efficiency of about 2.0% or greater, a fill factor of about 40% or greater, and/or an open circuit voltage of about 0.6 V or greater. In some embodiments, the present compounds also can be processed into very efficient solar cells without a thermally annealing step, thus providing time- and cost-saving benefits and allowing a larger variety of materials to be used in various components of the solar cell.
[0054] More specifically, the present teachings provide various conjugated oligomeric and polymeric compounds, where each compound includes a repeat unit that can be represented by the formula:

In certain embodiments, Ra, at each occurrence, independently can be selected from a C6_40 alkyl group, a C6_40 alkenyl group, and a C6_40 haloalkyl group, each of which can be linear or branched. In particular embodiments, Ra, at each occurrence, independently can be a C6_40 alkyl group or a C6_40 haloalkyl group, which can be either linear or branched. For example, Ra can be a branched alkyl group selected from:
where Ra> and Ra", independently are a linear Ci-20 alkyl group. In certain embodiments, Ra can be a linear or branched C2_40 alkenyl group (such as the linear or branched Ci_40 alkyl groups specified above but with one or more -CH2CH2- groups replaced by -CH=CH- groups).

It will be appreciated that where typical or preferred process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions can vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures.

In addition, a compound can be considered ambient stable if the optical absorption of the corresponding film does not vary more than 20% (preferably, does not vary more than 10%) from its initial value after exposure to ambient conditions, including air, humidity and temperature, over a 3 day, 5 day, or 10 day period.

In some embodiments, semiconductor materials incorporating one or more compounds of the present teachings can exhibit p-type semiconductor activity, ambipolar activity, light absorption, and/or light emission.
[0091] The present teachings, therefore, further provide methods of preparing a semiconductor material. The methods can include preparing a composition (e.g., a solution or dispersion) that includes one or more compounds disclosed herein dissolved or dispersed in a liquid medium such as a solvent or a mixture of solvents, depositing the composition on a substrate to provide a semiconductor material precursor, and processing (e.g., heating) the semiconductor precursor to provide a semiconductor material (e.g., a photoactive layer) that includes a compound disclosed herein.

In some embodiments, the composition can further include one or more additives independently selected from viscosity modulators, detergents, dispersants, binding agents, compatibilizing agents, curing agents, initiators, humectants, antifoaming agents, wetting agents, pH modifiers, biocides, and bacteriostats. For example, surfactants and/or polymers (e.g., polystyrene, polyethylene, poly-alpha-methylstyrene, polyisobutene, polypropylene, polymethylmethacrylate, and the like) can be included as a dispersant, a binding agent, a compatibilizing agent, and/or an antifoaming agent. In some embodiments, the depositing step can be carried out by printing, including inkjet printing and various contact printing techniques (e.g., screen-printing, gravure printing, offset printing, pad printing, lithographic printing, flexographic printing, and microcontact printing).

In various embodiments, the bulk heterojunction solar cells according to the present teachings can incorporate a blend material (e.g., a blended thin film) including a compound of the present teachings as the donor material and an acceptor material as the photoactive layer.
[0095] Typical acceptor materials include fullerene-based compounds. Fullerenes useful in the present teachings can have a broad range of sizes (number of carbon atoms per molecule). The term fullerene as used herein includes various cage-like molecules of pure carbon, including Buckministerfullerene (Ceo) "bucky ball" and the related "spherical" fullerenes as well as carbon nanotubes. Fullerenes can be selected from those known in the art ranging from, for example, C20-C1000. In certain embodiments, the fullerene can be selected from the range of C60 to C96. In particular embodiments, the fullerene can be C60 or C70, such as [6O]PCBM, or [7O]PCBM. In some embodiments, chemically modified fullerenes can be used, provided that the modified fullerene retains acceptor-type and electron mobility characteristics. Other acceptor materials can be used in place of fullerenes, provided that they have the required acceptor-type and electron mobility characteristics. For example, the acceptor material can be various organic small molecules, polymers, carbon nanotubes, or inorganic particles (quantum dots, quantum rods, quantum tripods, TiO2, ZnO etc.).
[0096] A photoactive component according to the present teachings can be prepared as a blended thin film deposited from a solution or dispersion containing a mixture of one or
more of the present compounds and an acceptor compound such as fullerene (e.g., PCBM).

The photoactive layer also can contain a polymeric binder, which can be present from about 5 to about 95% by weight. The polymeric binder, for example, can be a semicrystalline polymer selected from polystyrene (PS), high density polyethylene (HDPE), polypropylene (PP) and polymethylmethacrylate (PMMA).

In some embodiments, an optional smoothing layer can be present between the anode and the photoactive layer.

This electrode layer can have a relatively rough surface, and a smoothing layer made of a polymer, typically PEDOT:PSS made electrically conductive through doping, can be applied on top of the electrode layer to enhance its surface morphology. The photoactive layer generally is made of two components as described above, and can have a layer thickness of, e.g., about 100 nm to a
few μm. Before a counter electrode is applied (cathode), an electrically insulating transition layer can be applied onto the photoactive layer. This transition layer can be made of an alkali halogenide, e.g., LiF, and can be vapor-deposited in vacuum.

[0121] Example 3 - Device Fabrication
[0122] Photovoltaic devices were fabricated and the characteristics of these devices were tested in air. The current-voltage (I-V) curves were obtained by a Keithley 2400 source-measure unit. The photocurrent was measured under simulated AMI .5G irradiation (100 mW crrf 2) using a xenon-lamp-based solar simulator (Newport 91160A 300W Class-A Solar Simulator, 2 inch by 2 inch uniform beam) with air mass 1.5 global
filter. The light intensity was set using a NREL calibrated silicon photodiode with a color filter.
[0123] Photovoltaic devices were fabricated incorporating HP9 and the bucky ball compound C70PCBM. Before device fabrication, patterned ITO-coated glass substrates were cleaned by ultrasonic treatment in detergent, de-ionized water, acetone, isopropyl alcohol sequentially, and UV-ozone treatment for 15 minutes. A PEDOT:PSS layer of about 40 nm thickness was spin-coated from an aqueous solution onto ITO coated glass substrates, followed by baking at 1500C for 30 minutes in the air. The polymer/PCBM mixture solution in chlorinated solvents (such as chloroform) was prepared at a concentration of 5:10 mg/ml. The solution was then stirred for ~2 hours at 4O0C in a glove box and was spin-coated on top of the PEDOT:PSS layer. The thickness of the active layer was about 100-300 nm. To complete the device fabrication, a thin layer of lithium fluoride (LiF) and 100 nm thickness of aluminum were successively deposited thermally under vacuum of ~10"6 Torr. The active area of the device was about 0.088 cm2. The devices were then encapsulated with a cover glass using a UV curable epoxy in the glove box. A power conversion efficiency ~ 4.09% was achieved. The device achieved high Voc and high FF at the same time (Voc ~ 0.72V and FF ~ 50%).
