Progress of BODIPY dyes with aggregation-induced emission

With the development of organic optoelectronic materials and bioimaging technology, the investigation of organic light-emitting materials with aggregation-induced emission (AIE) properties has gradually become a hot spot in material science field. The fluoroborondipyrromethenes (BODIPY) dyes have become one of the research objects of AIE materials due to their excellent luminescence properties. This paper reviews the recent advances in the design and synthesis of AIE-type BODIPY derivatives, the mechanism of AIE properties and their promising applications in fluorescence imaging, gas sensing, photodynamic therapy, and mechanofluorochromic materials. It aims to explore the structure-activity relationship of AIE-type BODIPY fluorescent molecules, and provides ideas for the further design, synthesis and potential applications of BODIPY-type aggregated luminescent materials through classification, analysis and summary.
