摘要: 用各种取代基取代咔唑已成为设计室温磷光(RTP)材料常用的分子设计策略,然而有效的取代基团仍然十分有限。本研究中,使用酰胺基团作为取代基对苯基咔唑上苯基的对位、间位和邻位进行取代,研究同分异构体间磷光性质的差异。这3种异构体晶体都表现出明亮和超长的RTP发射,在紫外光激发下分别具有长达102,076和089 s的超长磷光寿命,使酰胺基团成为一种新的有效的RTP促进策略。

Abstract: Replacing carbazole with various substituents has become a common molecular design strategy for designing Room Temperature Phosphorescence (RTP) materials, but effective substituents are still very limited. In this study, we used a carbamoyl group as a substituent to replace the para-, meta-, and ortho-phenyl on-phenylcarbazole for the first time to study the differences in phosphorescent properties between isomers. All three isomer crystals exhibit bright and ultra-long RTP emissions, with ultra-long phosphorescent lifetimes of up to 102, 076 and 089 s respectively under ultraviolet excitation, making the carbamoyl group a new and effective RTP promotion strategy.
Key words: room temperature phosphorescence; carbazolyl derivative; carbamoyl; long life
