摘　　要：设计合成了含三氟甲基8-羟基喹啉衍生物配体(E)-2-[2-(2-三氟甲基苯基)乙烯基]-8-羟基喹啉(4)及其相应的锌配合物5,产物经1H NMR,IR,MS和元素分析进行了结构表征。利用X射线单晶衍射仪测定了配体L(4)的单晶结构,发现其具有独特的螺旋形结构。通过核磁滴定以及紫外和荧光滴定模拟了配体L(4)在溶液中与金属锌的配位过程,荧光光谱显示在甲醇溶液中配体的λmax=474 nm(蓝色),配合物的λmax=601 nm(橙黄色)。同时测定了配体和配合物的固体荧光寿命,两者的荧光寿命分别为15.6 ms和18.1 ms。A novel 8-hydroxyquinoline derivative ligand containing trifluoromethylbenzene Group： （E）-2-[2-（2- trifluromethylphenyl）vinyl]-8-hydroxyquinoline（4） and its zinc complex（5） have been synthesized and identified by lH NMR, FFIR, MS techniques and elemental analyses. The crystal structure of ligand 4 was determined by X-ray single crystal diffraction, and its network structure is special spiral. The aggregation behavior of Zn（AcO）2· 2H2O and the ligand 4 in solvents was investigated by UV-Vis, fuorescence spectrum and 1H NMR spectra titration. Fluorescence emission results showed that the λmax of ligand 4 and complex 5 were 474 nm and 601 nm, respectively. The fluorescence lifetime of ligand 4 and complex 5 were investigated in the solid state, their values are 15.6 ms and 18.1 ms, respectively. CCDC： 910120.
