Abstract

Aggregation-induced emission (AIE) is an unusual fluorescent phenomenon characterized by strong luminescence observed in the aggregated state or in high-concentration solutions. AIE-active polymers have been extensively explored for various applications. Owing to their unique AIE property, these polymers overcome the aggregation caused quenching effect observed in conventional organic dyes. This makes the AIE-active polymers especially attractive for biomedical applications due to the aggregation of AIEgens in aqueous solution. AIE-active polymers have shown great potential for chemical/biological sensors, biological imaging, multimodel imaging, drug delivery, nanotheranostics, and organic light emission diodes owing to their outstanding properties such as ultrabrightness, versatile design, and multifunctional potential. This article presents recent advances in the fabrication strategies and biomedical applications of AIE-active polymers.
