受体稠合构建cis/trans多π堆叠TSCT发光体，窄带OLED外量子效率达37.0%
cis/trans ‐Through‐Space Charge‐Transfer Isomers Enabled by Acceptor Fusion for High‐Efficiency Thermally‐Activated Delayed Fluorescence and Circularly Polarized Emission
AI 导读
研究者通过稠合两个单π堆叠TSCT单元的受体，得到cis-2D/A与trans-2D/A两种顺反异构的多π堆叠TSCT发光体，其中trans异构体具有本征手性并以(R,R)/(S,S)对映体形式存在。
推荐理由
原文给出cis/trans异构TSCT发光体的EQE与电致发光不对称因子，可对照圆偏振窄带OLED的效率区间。
创新点
把两个单π堆叠TSCT单元的受体稠合，一次得到顺反异构的多π堆叠TSCT发光体，其中trans异构体自带本征手性，从而在同一分子骨架下同时获得加速的辐射衰减与圆偏振发射。
