摘要：

A novel carbazole-triazole derivative was used as a bipolar host of a phosphorescent blue organic light-emitting diode doped with bis[2-(4,6- difluorophenyl)pyridinato-C2,N](picolmato)iridmm(III) (FIrpic). Maximum current efficiency, power efficiency, and external quantum efficiency of this blue phosphorescent OLED reached 50.30 cd/A and 25.03%, respectively. Efficiency roll-off was alleviated due to the wide recombination zone, and current efficiency slightly reduced to 46.67 cd/A at 1000 cd/m2. © 2014 Society for Information Display.
