Definitions

  • the claimed invention was made by, on behalf of, and/or in connection with one or more of the following parties to a joint university corporation research agreement: Regents of the University of Michigan, Princeton University, University of Southern California, and the Universal Display Corporation. The agreement was in effect on and before the date the claimed invention was made, and the claimed invention was made as a result of activities undertaken within the scope of the agreement.
  • the present invention relates to compounds for use as host materials or electron transporting materials, and devices, such as organic light emitting diodes, including the same.
  • Opto-electronic devices that make use of organic materials are becoming increasingly desirable for a number of reasons. Many of the materials used to make such devices are relatively inexpensive, so organic opto-electronic devices have the potential for cost advantages over inorganic devices. In addition, the inherent properties of organic materials, such as their flexibility, may make them well suited for particular applications such as fabrication on a flexible substrate. Examples of organic opto-electronic devices include organic light emitting diodes/devices (OLEDs), organic phototransistors, organic photovoltaic cells, and organic photodetectors. For OLEDs, the organic materials may have performance advantages over conventional materials. For example, the wavelength at which an organic emissive layer emits light may generally be readily tuned with appropriate dopants.
  • OLEDs make use of thin organic films that emit light when voltage is applied across the device. OLEDs are becoming an increasingly interesting technology for use in applications such as flat panel displays, illumination, and backlighting. Several OLED materials and configurations are described in U.S. Pat. Nos. 5,844,363, 6,303,238, and 5,707,745, which are incorporated herein by reference in their entirety.
  • phosphorescent emissive molecules is a full color display. Industry standards for such a display call for pixels adapted to emit particular colors, referred to as “saturated” colors. In particular, these standards call for saturated red, green, and blue pixels.
  • the OLED can be designed to emit white light. In conventional liquid crystal displays emission from a white backlight is filtered using absorption filters to produce red, green and blue emission. The same technique can also be used with OLEDs.
  • the white OLED can be either a single EML device or a stack structure. Color may be measured using CIE coordinates, which are well known to the art.
  • a green emissive molecule is tris(2-phenylpyridine) iridium, denoted Ir(ppy) 3 , which has the following structure:
  • organic includes polymeric materials as well as small molecule organic materials that may be used to fabricate organic opto-electronic devices.
  • Small molecule refers to any organic material that is not a polymer, and “small molecules” may actually be quite large. Small molecules may include repeat units in some circumstances. For example, using a long chain alkyl group as a substituent does not remove a molecule from the “small molecule” class. Small molecules may also be incorporated into polymers, for example as a pendent group on a polymer backbone or as a part of the backbone. Small molecules may also serve as the core moiety of a dendrimer, which consists of a series of chemical shells built on the core moiety.
  • the core moiety of a dendrimer may be a fluorescent or phosphorescent small molecule emitter.
  • a dendrimer may be a “small molecule,” and it is believed that all dendrimers currently used in the field of OLEDs are small molecules.
  • top means furthest away from the substrate, while “bottom” means closest to the substrate.
  • first layer is described as “disposed over” a second layer, the first layer is disposed further away from substrate. There may be other layers between the first and second layer, unless it is specified that the first layer is “in contact with” the second layer.
  • a cathode may be described as “disposed over” an anode, even though there are various organic layers in between.
  • solution processible means capable of being dissolved, dispersed, or transported in and/or deposited from a liquid medium, either in solution or suspension form.
  • a ligand may be referred to as “photoactive” when it is believed that the ligand directly contributes to the photoactive properties of an emissive material.
  • a ligand may be referred to as “ancillary” when it is believed that the ligand does not contribute to the photoactive properties of an emissive material, although an ancillary ligand may alter the properties of a photoactive ligand.
  • a first “Highest Occupied Molecular Orbital” (HOMO) or “Lowest Unoccupied Molecular Orbital” (LUMO) energy level is “greater than” or “higher than” a second HOMO or LUMO energy level if the first energy level is closer to the vacuum energy level.
  • IP ionization potentials
  • a higher HOMO energy level corresponds to an IP having a smaller absolute value (an IP that is less negative).
  • a higher LUMO energy level corresponds to an electron affinity (EA) having a smaller absolute value (an EA that is less negative).
  • the LUMO energy level of a material is higher than the HOMO energy level of the same material.
  • a “higher” HOMO or LUMO energy level appears closer to the top of such a diagram than a “lower” HOMO or LUMO energy level.
  • a first work function is “greater than” or “higher than” a second work function if the first work function has a higher absolute value. Because work functions are generally measured as negative numbers relative to vacuum level, this means that a “higher” work function is more negative. On a conventional energy level diagram, with the vacuum level at the top, a “higher” work function is illustrated as further away from the vacuum level in the downward direction. Thus, the definitions of HOMO and LUMO energy levels follow a different convention than work functions.
  • Indolocarbazole and oligophenylenes have excellent charge-transport properties, useful for organic electronic devices. Thus, there is a need in the art for novel indolocarbazole, oligophenylenes, and indolocarbazole-oligophenylenes to be used in organic electronic devices.
  • a compound having a formula selected from the group consisting of:
  • R is selected from the group consisting of:
  • R 4 is selected from the group consisting of alkyl, alkoxy, silane, aryl, heteroaryl, and combinations thereof;
  • R 1 , R 2 and R 3 each independently represents mono to maximum allowable substitutions, or no substitution;
  • R 1 , R 2 and R 3 are each independently selected from the group consisting of hydrogen, deuterium, alkyl, alkene, alkyne, alkoxy, halogen, silane, nitrile, nitro, aryl, heteroaryl and combinations thereof;
  • R 4 , R 1 , R 2 , and R 3 are each independently, optionally, further substituted with one or more substituents selected from the group consisting of hydrogen, deuterium, alkyl, alkene, alkyne, alkoxy, halogen, silane, nitrile, nitro, aryl, heteroaryl, and combinations thereof; and
  • an organic light emitting diode/device is also provided.
  • the OLED can include an anode, a cathode, and an organic layer, disposed between the anode and the cathode.
  • the organic layer can include a compound having a formula selected from the group consisting of Formula I and Formula II.
  • the organic light emitting device is incorporated into a device selected from a consumer product, an electronic component module, and/or a lighting panel.
  • the invention provides a formulation comprising a compound having a formula selected from the group consisting of Formula I and Formula II.
  • FIG. 1 shows an organic light emitting device
  • FIG. 2 shows an inverted organic light emitting device that does not have a separate electron transport layer.
  • an OLED comprises at least one organic layer disposed between and electrically connected to an anode and a cathode.
  • the anode injects holes and the cathode injects electrons into the organic layer(s).
  • the injected holes and electrons each migrate toward the oppositely charged electrode.
  • an “exciton,” which is a localized electron-hole pair having an excited energy state is formed.
  • Light is emitted when the exciton relaxes via a photoemissive mechanism.
  • the exciton may be localized on an excimer or an exciplex. Non-radiative mechanisms, such as thermal relaxation, may also occur, but are generally considered undesirable.
  • the initial OLEDs used emissive molecules that emitted light from their singlet states (“fluorescence”) as disclosed, for example, in U.S. Pat. No. 4,769,292, which is incorporated by reference in its entirety. Fluorescent emission generally occurs in a time frame of less than 10 nanoseconds.
  • FIG. 1 shows an organic light emitting device 100 .
  • Device 100 may include a substrate 110 , an anode 115 , a hole injection layer 120 , a hole transport layer 125 , an electron blocking layer 130 , an emissive layer 135 , a hole blocking layer 140 , an electron transport layer 145 , an electron injection layer 150 , a protective layer 155 , a cathode 160 , and a barrier layer 170 .
  • Cathode 160 is a compound cathode having a first conductive layer 162 and a second conductive layer 164 .
