Abstract
The invention relates to electrodes, which comprise spherical allotropes, particularly silicon and/or carbon nanotubes, and to the use thereof in organic semiconductor technology. The electrodes can either exclusively contain allotropes and/or contain allotropes that are embedded in an organic functional polymer.
Description
The present invention relates to comprise spherical allotropism (shape) body, particularly silicon-and/or carbon-nanotube electrode and application in the organic semiconductor technology thereof.
Known PANI, PEDOT:PSS (polystyrolsulfon acid) etc. can be used as the electrode of optoelectronic component for the organic conductor on basis from DE10126859.9.
It is known from DE1015316.0 that nanotube through deriving and spherical allotropism (shape) body and function are made (light) electronic component.
The work functions of the conductivity of this class electrode, light transmission, electronics and/or surface characteristic can also be optimized.
So on the organic substance basis, exist initiative novel and better the demand of electrode be used for so-called " polymer-electronics ", promptly by a branch of the electronics of traditional semiconductor technology as the realization of materials such as silicon, germanium.
Thereby task of the present invention is to provide a kind of electrode novel and that make moderate progress for organic semiconductor device and optoelectronic component on its (light) Electronic Performance.
Object of the present invention comprises and is used for photoelectronic-and/or the electrode of organic-semiconductor element, comprises isomer.
The present invention also for example is combined into a translucent or opaque electrode with organic conductor or semiconductor (being typically conjugated polymer) with isomer.
Electrode can comprise or as the metallic conduction form or as the isomer of semiconductive form.The example of the isomer of metallic conduction is from document (Z.F.Ren, Z.P.Huang, J.W.Xu, D.Z.Wang, J.H.Wang, L.Calvet, J.Chen, J.F.Klemic and M.A.Reed, " Large Arrays of Well-Aligned CarbonNanotubes Proceedings of 13
ThInternational Winter School on ElectronicProperties of Nove Materials, P.263-267 (1999)) in known.
Nanotube has electronics, optics and performance mechanics of a lot of uniquenesses.The hot strength height of single-walled nanotube, become metallic, semiconductive or insulating properties according to its diameter and chirality.In order to utilize these characteristics that nanotube is imposed chemically derived modification in nanometer technology is used is significant.Because it can influence its dissolubility and processability, particularly, can be used as the part phase mixture in the organic functions polymer of microelectric technique through nanotube that derive and/or dissolving.
Spherical isomer such as nanotube have been described silicon and carbon-nanotube for example at Nature1991.vol.354 among the P56-58.
Isomer can or join in the conductive organic material and/or on matrix and draws.Electrode can be realized with the isomer of simple metal or by composite material metallic isomer and/or that contain the semiconductive isomer.
By in advance on the matrix as glass, metal (molybdenum), semiconductor (silicon) or on film (PET), adhere to a kind of suitable catalyst, the isomer that is generated just is being suitable for/negative electrode, selects the composition of two kinds of compositions of following classification just also being suitable for/negative electrode at least:
-conductive matrix (conductive oxide (ITO)),
-semiconductor (silicon, germanium through mixing ...),
-metal species such as aluminium, silver ... or
-at non-conductive matrix (glass, film ...) go up the coating isomer, it or with pure state or to contain conduction or non-conductive jointing material (high polymer ...) form of mixture exists.
The notion of " organic material " or " functional polymer " comprises organically herein, metal is organic and/or all kinds of (mixed complex) plastics of organic and inorganic, especially uses those expressed materials of " plastic " in English.Here relate to except that semiconductor (silicon, germanium) that forms conventional diode and all substances classification the typical metal conductor.Therefore not predetermined those organic materials that are confined on the doctrine meaning as carbonaceous material.And more to consider widely used for example polysiloxanes.This technology does not limit the consideration bulk of molecule in addition, particularly is subjected to high polymer and/or oligomer material institute subordinate, can use " micromolecule " fully yet.The meaning of word composition of " high polymer " has its historical limitation in functional polymer.Thereby just in this point, there is not the implication of actual polymeric compounds.Can think as functional polymer semiconductive, material conduction and/or insulating properties.
The conductive electrode that (generation) metal isomer of growing up on matrix or nanotube provide distinctive three-dimensional structure, the for example upright thereon two-dimensional array that big nano surface pipe is arranged, the surface increases, promptly be covered with the stromal surface and the ratio that can utilize the surface (active surface) of electrode of isomer, can be by the density of plantation, i.e. the density of the isomer of Cheng Changing and/or further improve by its length.
The composite material that is used for electrode can be for example by embedding the preparation of metal isomer at the matrix of being made of the functional polymer of conduction.In the mixture of this isomer and organic functions high polymer, can be optimized the quantity of isomer, its concentration in matrix, the conductivity and/or the transparency of electrode.For example can be used as solution with this composite material and be printed to an electrode.
As the positive electrode (electronics is led) that heterojunction is used, also can particularly adopt the isomer of semiconduction.Showed not long ago that the compound of being made up of nanotube that contains conjugated polymer demonstrated high light electrical effect (S.B.Lee, T.Karayama, H.Aralo AndK.Yoshino, Synth.Met.121 (2001) 1591-1592)
Be used for photoelectronic element, Organic Light Emitting Diode (OLEDS) for example also comprises the optical property of the electrode of organic solar batteries and photodetector making it to adapt by the length that changes isomer.The isomer of suitable length or nanotube, just as the effect of λ/4 antennas, it can absorb electromagnetic radiation.In order to realize absorbing wavelength of visible light scope (400-800nm) with isomer, then adopt isomer with 100-200nm length.
The present invention is further elaborated by example below:
