Aggregation-induced emission: materials, mechanism, and applications

It has been a textbook knowledge that chromophore aggregation generally quenches light emission. The conceptualization of aggregation-induced emission (AIE) breaks this common belief and provides a new stage for the exploration of practically useful luminescent materials for optical, electronic, energy and biomedical applications.


Aggregation-induced emission (AIE) stands for an intriguing phenomenon that a series of non-emissive molecules in solutions are induced to emit strongly in the aggregate or solid state. Since the concept was first coined in 2001, the surging interest in AIE research has led to diverse AIE luminogens (AIEgens) with tunable emissions and high quantum yields approaching unity in the solid state. The weak emission of AIEgens as molecular species and their bright fluorescence as nanoscopic aggregates differentiate them from conventional organic luminophores and inorganic nanoparticles, making them ideal candidates for optical, electronic, energy and biomedical applications. AIE has been ranked #2 in research fronts for chemistry and materials science by Thomson Reuters in 2015, and the research field is expanding significantly in recent years, as evidenced by the exponentially increasing numbers of citations (e.g. 11,000 in 2014, 20,000 in 2015 and 28,000 in 2016) on this theme. In recognizing the increasing importance and activity of AIE research, we propose a symposium to focus on the development of new generations of AIEgens, understanding of the AIE mechanisms and the exploration of advanced technological applications, which will enable this exciting research area to develop further. This symposium will bring together researchers in the field to discuss the progresses, challenges and potential breakthroughs, with the hope that the booming development of AIE materials will shape the future of luminescent materials. We expect to attract around 100-120 abstracts from scientists of over twenty countries.

Hot topics to be covered by the symposium:

This Symposium will represent the latest development in the field of AIE research. 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 AIEgens with stimuli-responsiveness (e.g., photo-, thermo-, piezo-, vapo-, acido-, chronochromisms) and the related mechanisms; (3) biocompatible AIE probes for sensing, imaging, diagnosis, therapy and other biomedical applications; and (4) applications of AIEgens in optoelectronic devices and clean energy.
