Aggregation-induced emission (AIE) refers to a photophysical phenomenon shown by a class of luminogenic materials that are non-emissive when they are genuinely dissolved in good solvents as molecules but become highly luminescent when they are clustered in poor solvents or solid state as aggregates. In this talk, I will present a brief summary on the recent progresses in the area of AIE research. We have conducted mechanistic analyses of AIE processes and unified the restriction of intramolecular motions (RIM) as the main cause for the AIE effects. We have derived RIM-based molecular engineering strategies for the design of new AIE luminogen (AIEgen) systems. Typical examples of the newly developed AIEgen systems and their high-tech applications as optoelectronic materials, chemical sensors and biomedical probes will be presented and discussed.
