Abstract:
1. A light emitting device comprising (i) an anode, (ii) a cathode and (iii) an emitter layer, arranged between and in direct or indirect contact with the anode and cathode, comprising at least one complex of-formula (I) wherein M is (Pt(II), Pd(II), Rh(I), Ir(I), or Au(III); R is an alkyl, alkenyl, alkynyl, heteroaryl or —SO n =m =2; wherein the proportion of complexes of formula (I) in the emitter layer is more than 10% by weight, based on the total weight of the emitter layer and wherein said device is insulated from the environment, so that ingress of gas from the environment into the emitter layer cannot occur; wherein two radicals CNR together form a radical CN—R″—NC, wherein R″ is selected from alkylene, alkenylene, alkynylene, arylene, heteroarylene, wherein R″ optionally contains one or more heteroatoms.
