摘要：

Two compounds, namely 2-(1H-benzo[d]imidazol-2-yl)-6-methoxyphenol (BIMP) and (E)-ethyl 2-cyano-3-(pyren-3-yl)acrylate (ECPA), were synthesized and characterized.BIMPportrayed an interesting feature of aggregation promoted enhancement of excited state intramolecular proton transfer (ESIPT) in water. On the other hand,ECPAshows AIE emission in solution. Steady state spectroscopic studies revealed that theBIMP-ECPAensemble in solution behaves as a white light emitter, whereBIMPacts as a donor andECPAas an acceptor. The mechanism operative behind the observed white light generation was revealed to be exciplex formation betweenBIMPandECPA. The current report is the first example of white light generation from two synthesized AIEgens through exciplex formation and hence holds its own merit for a smart choice of synthesized compounds resulting in white light generation.
