Abstract Poly (phenylacetylene) s containing pendant phosphorescent iridium complexes have been synthesized and their electrochemical, photo-and electroluminescent properties studied. The polymers have been synthesized by rhodium-catalyzed copolymerization of 9- (4-ethynylphenyl) carbazole (CzPA) and phenylacetylenes (C∧ N) 2 Ir (κ 2-O, O′-MeC (O) CHC (O) C 6 H 4 C [TRIPLE BOND] CH-4)(C∧ N= κ 2-N, C 1-2-(pyridin-2-yl) phenyl (Ir ...
