Abstract

A novel ancillary ligand (2-(1-hydroxy-naphthyl)-benzothiozolato) (HNBT) and corresponding iridium(III) complex, Ir(ppy)2(NBT) (ppy 2-phenylphridine) are synthesized, and red-emitting electrophosphorescent devices by doping Ir(ppy)2(NBT) in 4,4′-N,N′-dicarbazole- biphenyl (CBP) are fabricated. the optimized device displays EL spectrum with a narrow full-width at half-maximum of 65 nm, and the Comission International de L'Eclairage (CIE) coordinates of (0.65, 0.33) are very close to those suggested by the National Television System Committee (NSTC) standard for a red emitter. © 2011 The Electrochemical Society.
