Organic electronic component and method for the production thereof
View Patent ↗An organic electronic component, including a substrate, a first electrode, a second electrode, an electron-conducting layer which is arranged such that it is electrically conductively connected to at least one of the electrodes, wherein the electron-conducting layer is obtained by joint vaporization of a metal complex with an organic compound.
1. An organic electronic component, comprising:
a substrate,
a first electrode,
a second electrode,
an electron-conducting layer which is arranged in such a way that it is electrically conductively connected to at least one of the electrodes,
wherein the electron-conducting layer is obtained by joint vaporization of a metal complex, which comprises a central metal atom, with an organic compound, wherein the organic compound comprises a heteroaromatic compound which is conjugated with an aromatic compound via a C—C bond.
2. The organic electronic component according to claim 1 , wherein the organic compound coordinates to the metal complex due to the joint vaporization.
3. The organic electronic component according to claim 1 , wherein the metal complex comprises more than one central metal atom.
4. The organic electronic component according to claim 1 , wherein the central metal atom or central metal atoms is/are selected from Cr, Mo or W.
5. The organic electronic component according to claim 1 , wherein the organic compound has the general formula:
wherein
the ring members A to F independently of each other represent C or one or two ring members can be N,
n is 2 to 8, wherein the free valences of the ends can be in each case independently of each other saturated by H, methyl, phenyl, 2-pyridyl, 3-pyridyl or 4-pyridyl,
R 1 to R 4 can be in each case independently of each other H, methyl, phenyl, 2-pyridyl, 3-pyridyl or 4-pyridyl and/or R 1 and R 2 or R 3 and R 4 can be connected together by butadiene or azabutadiene units, and can be connected between the nth and (n+1)th ring by ethylene or azomethine units, whereupon phenanthrene or aza-phenanthrene units are formed.
6. The organic electronic component according to claim 1 , wherein the organic compound is selected from:
7. The organic electronic component according to claim 1 , wherein the organic compound is selected from:
8. The organic electronic component according to claim 1 ,
wherein at least parts of the organic compounds bridge two metal complexes together, so that a chain-like structure of the metal complexes is formed and/or at least parts of the organic compounds bridge more than two metal complexes together, so that a network-like structure of the metal complexes is formed.
9. The organic electronic component according to claim 1 , which is formed as an organic LED (OLED) which additionally comprises an organic emitting layer.
10. A method for manufacturing an organic electronic component, comprising the method steps of:
A) providing a substrate,
B) applying a first electrode,
C) depositing an electron-conducting layer on the substrate,
D) applying a second electrode,
wherein the electron-conducting layer is deposited by means of simultaneous vaporization of a metal complex and an organic compound, wherein the organic compound comprises a heteroaromatic compound which is conjugated with an aromatic compound via a C—C bond.
11. The method according to claim 10 , wherein during the simultaneous vaporization the organic compound coordinates in the gas phase to the metal complex.
12. The method according to claim 10 , wherein the electron-conducting layer is deposited as a chain-like or network-like structure.
13. The method according to claim 12 , wherein the degree of cross-linking of the electron-conducting layer is controlled by the ratio between the metal complex and the organic compound during vaporization.
14. The method according to claim 10 , wherein the organic compound does not coordinate to the metal complex prior to vaporization.
