New poly(4,4′-dicyano-4″-vinyl-triphenylamine) host material for single-layer Ir complex phosphorescent light-emitting devices

We report a new host material for iridium complex light-emitting devices, poly(4,4′-dicyano-4″-vinyl-triphenylamine) (PCNVTPA), which was synthesized by nitroxide-mediated free radical polymerization. The incorporation of electron-withdrawing cyano groups led to a significant variation in electronic...
