Copper(I)complexes are new. Copper(I)complexes of formula (A) are new. X : Cl, Br, I, CN and/or SCN; NarcE : a bidentate ligand (B1), nitrogen containing aryl group of formula (B1a)-(B1d), where the substituent is linear, branched or cyclic long-chain 1-30C-alkyl, linear, branched or cyclic long-chain 1-30C-alkoxy, linear or branched long-chain or cyclic 1-30C-perfluoroalkyl or short-chain polyethers with a chain length of 3-50 repeating units, where NarcE is an optionally substituent, which increases the solubility of (I) in an organic solvent; E : phosphanyl/arsenyl containing group of formula R 2>E; R : alkyl, aryl, alkoxy, phenoxy or amide; N : imine function which is a component of 5-membered N-heteroaryl ring consisting of triazole, oxadiazole, thiadiazole, tetrazole, oxatriazole or thiatriazole; arc : at least one carbon atom that is likewise a component of the aryl group, where C atom being directly adjacent to both the imine nitrogen atom and to P or Ar atom; Y 1>NR 2>, O or S; and either R 1>-R 3>H, halo, a substituent bonded over O, N or Si, linear, branched or cyclic alkyl, aryl, heteroaryl, alkenyl and/or alkynyl, or substituted branched or cyclic alkyl, aryl, heteroaryl and/or alkenyl groups substituted with halo or D, or branched or cyclic alkyl or further donor or acceptor groups e.g. amines, carboxylates or their esters or CF 3; or R 2>R 3>optionally forms a fused ring system. Where: NarcE optionally comprises at least one substituent (Q) for increasing the solubility of (A) in an organic solvent, and (Q) is linear, branched or cyclic 1-30C-alkyl, 1-30C-alkoxy, 1-30C-perfluoroalkyl and short chain polyether with 3-50 repeating units. Independent claims are included for: (1) the preparation of (I); (2) an optoelectronic component comprising (A); (3) the preparation of the optoelectronic component using (A); (4) the bidentate ligand (B1); and (5) the preparation of the bidentate ligand (B1) comprising reacting a nitrogen containing aryl compound of formula (B1aa)-(B1dd) with a chlorinated compound of formula (E(R 1>) 2Cl) in the presence of a base to obtain (B1a)-(B1d), respectively.
