Copper(I) complexes (I) are new. Copper(I) complexes of formula (I) are new. Cu : Cu(I); X : Cl, Br, I, SCN, CN, and/or (R6-triple bond); R6 : R; P-N : phosphine ligand of formula (II) (substituted with N-heterocyclic phosphine, preferably aromatic 6- or 5-membered ring of formula (IIIa)-(IIIt); E : C or N; E 1 : C or N, which are not substituted with H; a, b : single- or double bond; R4, R5 : (CH 3-(CH 2) n) (optionally branched or cyclic) or (hetero)aryl (optionally substituted with alkyl, halo preferably F, Cl, Br or I, -SiR7, or -OR7); n : 0-20, preferably more than 6, where R4 and R5 are directly attached to P of (II); R7 : R1; R : aryl, preferably phenyl, alkenyl or alkynyl (all optionally substituted with alkyl, halo, preferably F, Cl, Br, or I, -SiR7, or -OR7), or (CH 3-(CH 2) n1-) (optionally branched or substituted with halo, preferably F, Cl, Br, or I); n1 : 0-20; either R1, R2, R3 : R or H; or R+R1+R2+R3 : optional fused ring systems, where R does not contain H. Independent claims are also included for: (1) use of (I) for emitting light, preferably in an emitter layer in an opto-electronic device; (2) producing an opto-electronic device using (I), comprising depositing (I) on a solid substrate, in a wet-chemical manner, by a colloidal suspension, or by sublimation; and (3) opto-electronic device comprising (I), which exhibits a distance between the lowest triplet state and the overlying singlet state of 50-2500 cm -1>.
