Abstract
Abstract 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‐C 2 , 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/m 2 .
