AbstractPolymer-based blue electrophosphorescent light-emitting diodes are reported by doping iridium(Ill) diazine complex (DFPPM)(2)Ir(pic) (DFPPM = 2-(2,4-difluorophenyl)-pyrimidine, pic = picolinate) in poly(vinylcarbazole) (PVK) as the source of emission. The iridium(Ill) diazine complex shows sky blue emission with its maximum emission peak at 476 nm originating from an admixture of triplet metal-to-ligand charge-transfer and ligand-centered states. The (DFPPM)(2)Ir(pic)-doped device furnishes a maximum external quantum efficiency of 2.2% and power efficiency of 1.9 lm/W at a 10 wt% doping concentration. (C) 2009 Elsevier B.V.
