设计合成了两种含三氟苯基的新型8-羟基喹啉衍生物配体：（ E）-2-[2-（2，4，6-三氟苯基）乙烯基]-8-羟基喹啉（B）、（E）-5-[2-（2，4，6-三氟苯基）亚胺基]-8-羟基喹啉（C）及其相应的锌配合物D与E，产物经NMR，IR，MS，元素分析等进行结构表征。通过核磁、紫外滴定跟踪了金属锌与配体的配位过程，并测定了两者溶液状态下的荧光性质：化合物D，E在甲醇溶液中的荧光发射峰位置分别在599 nm和572 nm处；相比于8-羟基喹啉，2位和5位取代8-羟基喹啉衍生物的荧光发生了明显红移。锌配合物固体荧光寿命的测定结果表明，配合物D表现出较长的荧光寿命。

Two 8-hydroxyquinoline derivatives of(E)-2-[2-(2,4,6-trifluorophenyl)vinyl]-8-hydrox-ylquinoline(B),( E)-5-[2-(2,4,6-trifluorophenyl)imino]-8-hydroxyquinoline( C)and their zinc complexes D and E were designed and synthesized,and identified by NMR,IR,MS spectra and elemental analysis. The aggregation behaviors of Zn( AcO)2 and the ligands B and C were inves-tigated by UV-vis spectrum in methyl solution. The luminescence properties of the compounds B and C were investigated by fluorescence spectra in methol solution at room temperature. The results showed that the fluorenscence peaks of compounds D and E were 599 nm and 572 nm,respectively. Their fluorescence properties showed that the luminescence wavelengths of 5-substitued-8-hydroxyquinoline derivatives and 2-substitued-8-hydroxyquinoline derivatives shift to red compared with that of 8-hydroxyquinoline. Meanwhile,the results for determination of solid fluorescence life-time showed that the complex of D had a long fluorescence lifetime.
