COPPER COMPLEXES FOR OPTOELECTRONIC APPLICATIONS

摘要

The invention relates to copper(I) complexes of the formula (A) with X = Cl, Br or I (independently of one another) N*?E = a bidentate ligand, with E = phosphanyl/arsenyl radical of the form R2E (where R = alkyl, aryl, alkoxy, phenoxy or amide); N* = imine function which is part of an aromatic group selected from pyridyl, pyrimidyl, pyridazinyl, triazinyl, oxazolyl, thiazolyl and imidazolyl, the aromatic group optionally having at least one substituent for increasing the solubility of the copper(I) complex in an organic solvent, and "?" = at least one carbon atom, which is likewise part of the aromatic group, the carbon atom being located both directly adjacent to the imine nitrogen atom and to the phosphorus or arsenic atom, and also to the use thereof in optoelectronic assemblies, especially in OLEDs.
