A D-π-A terpyridine derivative DY was designed and synthesized by Witting reaction using 4-n-butoxy-benzaldehyde as electron donor and terpyridine as electron acceptor.Its zinc(Ⅱ)complex DY-Zn was synthesized by reacting with Zn(NO3)2·6H2O.The structures of DY and DY-Zn were characterized by 1H NMR spectroscopy and infrared spectroscopy.The optical properties of UV-vis absorption spectra and fluorescence emission spectra were studied.The results demonstrated that complex DY-Zn has good aggregation-induced enhanced emission properties,and the fluorescence intensity reaches the highest value when the water content is 80％,while compound DY exhibits an aggregation-induced quenching properties.
