Highly efficient blue and green thermally activated delayed fluorescence (TADF) molecules bearing trifluoromethane-modified carbazole groups were developed. The trifluoromethane groups on carbazole induced blue-shifted emission and improved the photoluminescence quantum yield. The photostability of the TADF molecules was strongly related to the modification position of trifluoromethane on carbazole.

用于高效蓝色有机发光二极管的热活化延迟荧光分子的三氟甲烷修饰

开发了带有三氟甲烷修饰的咔唑基团的高效蓝色和绿色热激活延迟荧光(TADF)分子。咔唑上的三氟甲烷基团引起蓝移发射并提高了光致发光的量子产率。TADF分子的光稳定性与三氟甲烷在咔唑上的修饰位置密切相关。
