The aggregation-induced emission (AIE) phenomenon was firstly reported by the Tang group in 2001, which has revolutionized the scientific fields of biological and optoelectronic materials in the past two decades. Due to importance of AIE, thousands of work has been published on developing the new efficient AIE luminogens (AIEgens) and implement the practical applications. Though the conical intersection, E/Z isomerization, proton transfer, charge transfer, intra- and inter molecular restrictions has been considered as the main reasons for the phenomenon of AIE systems, few direct evidence have been found to support those hypotheses.
