The synthesis of two random copolymers bearing pendant mixed-ligand orthometallated terpyridine-based cationic iridium (III) complexes, as well as their uses as single-layered electrophosphorescent emitters in polymer light-emitting diodes is described. Both solution-processable iridium metallopolymers are prepared by copolymerization of styrene with a complex-substituted styrene by nitroxide mediated polymerization. Results on devices based on metallopolymers used as dopant of poly(N-vinylcarbazole) or alone as single layers are presented.
