Aggregation-induced emission: phenomenon, mechanism and applications.

摘要: It is textbook knowledge that chromophore aggregation generally quenches light emission. In this feature article, we give an account on how observed opposite phenomenon termed aggregation-induced emission (AIE) and identified the restriction of intramolecular rotation as a main cause for AIE effect. Based mechanistic understanding, developed series new fluorescent phosphorescent systems with colours covering entire visible spectral region luminescence quantum yields up to unity. We explored high-tech applications luminogens as, example, fluorescence sensors (for explosive, ion, pH, temperature, viscosity, pressure, etc.), biological probes protein, DNA, RNA, sugar, phospholipid, immunoassay markers, PAGE visualization agents, polarized emitters, monitors layer-by-layer assembly, reporters micelle formation, multistimuli-responsive nanomaterials, active layers in fabrication organic light-emitting diodes.
