A Simple, Easy Preparation and Tunable Strategy for Preparing Organic Room-Temperature Phosphorescence.

Eye-catching organic room-temperature phosphorescence (RTP) is becoming more and more universal through various strategies, such as crystal engineering, macrocyclic inclusion, host-guest doping, and copolymerization. It is always the pursuit of researchers to prepare high-efficiency RTP materials by the simplest strategy. The doping strategy is one of the most simple and effective strategies and involves mixing phosphor with rigid host material. The principle of the doping RTP system has developed from a conventional rigidity effect of the host through the host-guest interaction. This perspective aims at multifunctional host materials and summarizes the recent development of doping organic RTP systems. Doping systems play more and more important roles in the development of long-afterglow and high-yield RTP materials. The application scenarios of RTP are becoming wider and wider.
