The AIE Journey:from Creative Science to Innovative Technology
Typical chromophores usually suffer from weakening or quenching of light emission caused by aggregation.This notorious photophysical effect is practically harmful because,in real-world applications,luminophores are commonly used in solid state or aqueous media,where chromophores tend to form aggregates.In 2001,we discovered a diametrically opposite phenomenon that some chromophores are non-emissive when dissolved but emissive upon aggregation.We termed this unusual process as aggregation-induced emission (AIE) and identified the restriction of intramolecular motion (RIM) as the main cause for the AIE eff ect.In the past 15 years,we not only developed a wide variety of AIE luminogens with broad emission range covering the visible and near-IR region but also explored their diverse high-tech applications in such areas as optoelectronic devices,chemo/biosensing,and biological imaging.
