Achieving purely organic room temperature phosphorescence in aqueous solution

Purely organic room temperature phosphorescence (RTP) materials have aroused increasing interests in recent years and been widely applied anti-counterfeiting, biological imaging, sensing, etc. Currently, these can be efficiently developed crystalline states amorphous polymer-doped systems. However, achieving RTP solution, especially water is still a formidable challenge. Recently, reports on aqueous phase some feasible design strategies proposed; however, related investigations are limited there lack of systematic reviews. Therefore, we summarized the cases emission with primarily focusing properties efficient (e.g., forming nanoparticles from phosphorescent molecules macrocyclic supramolecular assembly). Moreover, promising applications bio-imaging sensing were discussed. Some detailed perspectives concerning application provided hope to provide inspiration for future development RTP.
