关 键 词:Polymer chemistry aggregation-induced emission
摘 要: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.
