摘要：

A carboline modified dibenzofuran compound, 2,8-bis(pyrido[2,3-b]indol-9-yl)dibenzofuran (DBFCb), was synthesized and evaluated as the host material for blue phosphorescent organic light-emitting diodes by doping iridium (III) bis((3,5-difluorophenyl)pyridine) picolinate (FIrpic) as a blue triplet emitter. The DBFCb host showed balanced charge density in the emitting layer and a triplet energy of 2.88 eV by carboline moiety. The Flrpic doped DBFCb devices realized high external quantum efficiency of 21.3% at a low doping concentration of 3%. (C) 2014 Elsevier Ltd. All rights reserved.
