Carbazole-benzonitrile derivatives as universal hosts for triplet-harvesting blue organic light-emitting diodes
Sook Hee Jeong, Seung Chan Kim, Jun Yeob Lee
Abstract
In this study, we proposed two carbazole-benzonitrile-based bipolar hosts, namely 2,6-bis(3-(9 H -carbazol-9-yl)phenoxy)benzonitrile and 2,6-bis(4-(9 H -carbazol-9-yl)phenoxy)benzonitrile, for improving the efficiency of blue phosphorescent organic light-emitting diodes.
