摘要

A bipolar compound (CTF) consisting of hole-transporting carbazole, electron-transporting 1,2,4-triazole, and spirofluorene was synthesized. It was blended with polyvinyl carbazole (PVK) to improve the performance of electrophosphorescent device [ITO/PEDOT:PSSI PVK+CTF:Ir(ppy)3/BCP(10 nm)/Ca(50 nm)/Al(100 nm)]. The maximum current efficiency was enhanced to 9.9 cd/A from 5.6 cd/A of PVK-based device.
