Dynamic organic room-temperature phosphorescent systems

Abstract

Organic room temperature phosphorescent (RTP) systems have attracted extensive interests due to their wide application scope. Unlike the nontunable photophysical properties of static phosphorescence materials, dynamic organic RTP materials exhibit “must answer to require” characters under external stimuli. On account of the reversible sensitivity, quick response, and easy control of dynamic RTP materials, they present advantages over conventional static ones. We herein review the latest research progress of dynamic organic RTP systems from direct visual monitoring of phosphorescence luminance and color changes under external stimuli and present major insight into the relationship between molecular answered modes and different response behavior. Some leading strategies for enhancing the RTP performance and tuning the phosphorescence colors are highlighted. The challenges and opportunities for the future studies of dynamic organic RTP materials are also discussed.
