摘　　要：以4-正丁氧基苯甲醛为电子给体,三联吡啶为电子受体,通过Witting成烯反应设计并合成了一种D-π-A构型的三联吡啶衍生物DY,并进一步与六水合硝酸锌反应,合成了一种锌(Ⅱ)配合物DY-Zn.通过核磁共振氢谱和红外光谱对化合物DY和DY-Zn的结构进行了表征.利用紫外-可见吸收光谱和荧光光谱研究了二者的光学性质.结果表明,配合物DY-Zn具有良好的聚集诱导荧光增强性质,在含水量为80%时,荧光强度达到最高值,而化合物DY表现出聚集诱导荧光淬灭性质.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(NO_(3))_(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.
