摘要

We developed four types of novel electron-transporting carbazolylphenyl-quinoline (CQ) derivatives. The photophysical and thermal properties of these materials were studied. Moreover, these materials were applied for an electron-transport layer and for a host material in phosphorescent organic light-emitting diodes, and a high electroluminescence (EL) efficiency was obtained in these devices. With 2-(3-(3,6-diphenylcarbazole-9-yl)phenyl)lepidine (DPCLP) as a host and tris(2-phenyl-pyridine)iridium(III) [Ir(ppy)3] as a guest, the highest EL efficiency of η_(ext) = 11.2% was obtained.
