Highly efficient solution processed blue phosphorescent organic light-emitting diodes were developed using a carbazole–dibenzofuran hybrid host material. Asymmetric carbazole–dibenzofuran hybrid host material was synthesized by coupling reaction of phenylcarbazole and dibenzofuran, and it showed good film morphology and bipolar charge transport properties after solution coating. Blue phosphorescent organic light-emitting diodes fabricated by spin coating exhibited extremely high quantum efficiency of 23.9%, which was better than any other data reported for solution processed blue phosphorescent organic light-emitting diodes.
