摘要：

Herein, 5H-benzofuro[3,2-c]carbazole (BFCz) was introduced into a multi-resonance skeleton to develop two asymmetric emitters, BFCz-B-Cz and BFCz-B-O, which exhibit narrowband green and blue emissions and enhanced reverse intersystem crossing rates. The corresponding pure green and blue OLEDs exhibit high external quantum efficiencies of 26.0% and 11.0%, respectively.
