Abstract
- Organic room temperature phosphorescent materials have attracted a lot of research interest due to their wide applications. Herein, a series of intramolecular-locked triphenylamine derivatives have been synthesized with adjustable room temperature phosphorescence (RTP) properties, in which the RTP lifetime ranged from 30 to 288 ms and the emission color varied from sky blue to green. These results are mainly related to the substituent effect, which can tune the intramolecular charge transfer and intermolecular interactions, contributing to different intersystem crossing (ISC) processes, and the stability and energy levels of excited triplet states.
