Copper complexes for optoelectronic applications

摘要

The invention relates to an optoelectronic component having a copper(I) complex of the formula:;
wherein X is independently selected from Cl, Br and I; N*∩E or E∩N* is a bidentate ligand connected to a first Cu atom via an N atom and connected to a second Cu atom via an E group, or a monodentate ligand connected to a Cu atom via an E group, wherein E is R2As or R2P, wherein R is selected from alkyl, aryl, alkoxy, and phenoxy; N* is a part of an aromatic group comprising an imine functional group, wherein the aromatic group is selected from pyridyl, pyrimidyl, pyridazinyl, triazinyl, oxazolyl, thiazolyl, imidazolyl, and fused N-heteroaromatics, and wherein the imine functional group comprises the N atom double bonded to a carbon atom of the aromatic group; and ∩ is a carbon atom, which is likewise part of the aromatic group, connected to the N atom of said aromatic group and also connected to the E group via the As or P atom of the E group.

1. An optoelectronic component comprising a copper(I) complex of formula A:wherein:
X=independently selected from Cl, Br and I; N*∩E or E∩N*=a bidentate ligand connected to a first Cu atom via an N atom and connected to a second Cu atom via an E group, or a monodentate ligand connected to a Cu atom via an E group wherein:
E=R2As or R2P, wherein R is selected from the group consisting of alkyl, aryl, alkoxy, and phenoxy;N*=part of an aromatic group comprising an imine functional group, wherein the aromatic group is selected from pyridyl, pyrimidyl, pyridazinyl, triazinyl, oxazolyl, thiazolyl, imidazolyl, and fused N-heteroaromatics, and wherein the imine functional group comprises the N atom double bonded to a carbon atom of the aromatic group; and∩=a carbon atom, which is likewise part of the aromatic group, connected to the N atom of said aromatic group and also connected to the E group via the As or P atom of the E group.
