Dynamic organic room-temperature phosphorescent systems

Abstract

Organic room-temperature phosphorescent (RTP) systems can be divided into dynamic and static organic phosphorescent materials based on their response mode to external stimuli. Dynamic organic phosphorescent materials are more useful compared with conventional static RTP materials owing to their reversible sensitivity, quick response, and ease of controlling their properties. With the rapid development of organic RTP systems, dynamic organic RTP materials are expected to meet the practical requirements. Herein, we review the recent research progress on dynamic organic RTP systems by (1) direct visual monitoring of phosphorescent intensity and color changes under external stimuli and (2) providing insights into the relationship between molecular response modes and different response behavior. In particular, strategies for enhancing RTP performance and tuning phosphorescence colors are highlighted. The prospects and future challenges in this promising field are also discussed to promote the further development of advanced dynamic organic RTP systems.
