Polymers with aggregation-induced emission characteristics

Abstract

With rapid development of aggregation-induced emission (AIE), AIE polymers have attracted great attention because of their outstanding properties such as intense fluorescence, easy processability, facile functionalization, structural diversity, and excellent thermal stability, which offer them with an extensive fields of applications. In this chapter, different synthetic strategies of AIE polymers will be summarized, mainly including post-functionalization and direct polymerization. After that, the widespread applications of AIE polymers in optoelectronic, sensing, and biological fields will be introduced. Although great progress has been made, more work can be done for further development of AIE polymers. As most of reported AIE polymers are based on TPE moiety, new AIE systems with various structures are highly desired, which possess high emission efficiency and broad emission spectrum.
