Aggregation Induced Emission: Materials and Applications (#444)

It has been a textbook knowledge that chromophore aggregation generally quenches light emission. The conceptualization of aggregation induced emission (AIE) breaks this common law and provides a new stage for the exploration of practically useful light-emitting materials. Since the concept was first coined in 2001, the surging interest in AIE research has led to the generation of diverse AIE luminogens (AIEgens) with tunable emissions and high quantum yields approaching unity in the solid state. The weak fluorescence of AIEgens as molecular species and bright fluorescence in the aggregates differentiate them from the conventional luminophores and inorganic nanomaterials (e.g., quantum dots), making them ideal candidates for optical, electronic, energy and biomedical applications. The establishment of clearer models and theorems for deeper understanding of AIE mechanisms, and the exploration of more high-tech applications based on AIEgens are expected to bring the technology to a newer height. To highlight the breakthrough, progress, and challenges in the design, synthesis and applications of AIEgens, we propose to focus on the following topics in this symposium: (1)Fluorescent and phosphorescent AIE-based polymers, oligomers and molecules; (2) Advanced functional AIEgens with stimuli-responsiveness (e.g., photo-, thermo-, piezo-, vapo-, acido-, chronochromisms) and the related mechanisms; (3)Biocompatible AIE probes for sensing, imaging and other biomedical applications; and (4) Applications of AIEgens in optoelectronic devices and clean energy.
