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. Organic RTP systems can be divided into stretchable and inelastic materials. Stretchable organic RTP materials exhibit more advantages in dynamic information encryption, human–computer interface, and biomedical sensing applications owing to their stretchability, fatigue resistance, and self-healing ability. They could solve the problems of rigid materials, which struggle to match dynamic environments and meet practical requirements. Herein, we review the recent research progress on stretchable organic RTP systems according to their construction strategy, including physical doping of phosphorescent chromophores into stretchable polymers 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.
