Abstract
In this study, we designed and synthesized three fluorescent blue emitting materials based on indenophenanthrene derivatives. These derivatives were synthesized by Suzuki coupling reaction. Particularly, a device C using 9,10-bis(9,9-dimethyl-9H-indeno[2,1-l]phenanthren-11-yl)anthracene as blue emitter showed maximum values of luminous efficiency, power efficiency, and external quantum efficiency of 7.58 cd/A, 5.87 lm/W, 4.20%, respectively.
