Stretchable organic room temperature phosphorescence systems

Abstract

Organic room temperature phosphorescent (RTP) materials, with their excellent properties such as high exciton utilization efficiency, long lifetime, and low toxicity, show promising application prospects in many key fields. The organic RTP systems could be divided into stretchable and inelastic materials. The stretchable organic RTP materials exhibit more advantages in dynamic information encryption, human-computer interface, and biomedical sensing owing to their stretchability, fatigue resistance, and self-healing ability. They could solve the problems those rigid materials are difficult to match the dynamic environment and meet practical requirements. Herein, we review the recent research progress on stretchable organic RTP systems according to the construction strategy, including doping phosphorescent chromophores in stretchable polymer physically and polymerization of phosphorescent chromophores with polymer monomers. Finally, the prospects and scientific challenges in this promising field are critically analyzed to provide helpful guidance for further development of advanced stretchable RTP systems.
