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.

基于5H-苯并呋喃[3,2-c]咔唑的不对称策略可实现高效的窄带多共振热激活延迟荧光发射器

在此，将 5 H-苯并呋喃并[3,2- c ]咔唑（BFCz）引入多共振骨架中，开发了两种不对称发射体BFCz-B-Cz和BFCz-BO，它们表现出窄带绿光和蓝光发射，并增强了反向系间穿越率。相应的纯绿色和蓝色 OLED 分别表现出 26.0% 和 11.0% 的高外量子效率。
