The present invention relates to copper (I) complexes of formula (A) A In the above formula X * is Cl, Br, I, CN, SCN, alkynyl and / or N 3 (independently of one another being shown below); N * ∩E is a bidentate ligand, where E is a phosphinyl / arsenyl group in the form of R 2 E (R = alkyl, aryl, alkoxyl, phenoxyl or amide); N * is a member of the N-heteroaromatic 5-membered ring selected from the group consisting of pyrazole, isoxazole, isothiazole, triazole, oxadiazole, thiadiazole, tetrazole, oxatriazole and thiatriazole. Functional group; "∩" is likewise at least one carbon atom that is a component of an aromatic group, and the carbon atom is located directly adjacent to both the imine nitrogen atom and the phosphorus or arsenic atom. |
