An electron transport type Host introduced novel terphenyl blockinig group for Blue Phosphorescent Organic Light-Emitting Diodes |
초록 |
An electron transport type host withstanding the positive polaron stress was synthesized using the terphenyl moiety with triazine core to develop high triplet energy host. The host was designed to have both the terphenyl blocking group and the hole transport type carbazole group. In the device application, the host was used as electron transport type host mixed with a hole transport type mCBP host in the blue PhOLEDs doped with CNImIr and Ir(cb)3 blue phosphors. the mCBP/tPhCzTrz mixed host showed high external quantum efficiency (EQE) over 20% at 1000 cd m−2 and low efficiency roll‐off in the blue phosphorescent organic light-emitting diodes. |
