中文摘要：

设计合成了3种8-羟基喹啉衍生物配体：（E）-2-[2-（2-硝基苯基）乙烯基]-8-羟基喹啉（4a）,（E）-2-[2-（3-硝基苯基）乙烯基]-8-羟基喹啉（4b）,（E）-2-[2-（4-硝基苯基）乙烯基]-8-羟基喹啉（4c）及其相应的锌配合物5a～5c,产物经1H NMR,IR,MS和元素分析技术进行了结构表征.通过紫外滴定模拟了金属锌与配体的配位过程,分别测定了它们固态和溶液状态下的荧光性质：光谱显示化合物5a～5c固体荧光光谱的λmax分别是596,625,592 nm,在DMF溶液中的λmax分别是562,536,618 nm.荧光光谱显示硝基位置的改变可以调控8-羟基喹啉锌配合物的发光性质.

英文摘要：

Three 8-hydroxyquinoline derivatives（E）-2-[2-（2-nitrophenyl）vinyl]-8-hydroxyquinoline（4a）,（E）-2-[2-（3-nitrophenyl）vinyl]-8-hydroxyquinoline（4b）,（E）-2-[2-（4-nitrophenyl）vinyl]-8-hydroxyquinoline（4c） and their zinc complexes 5a～5c have been synthesized and identified by 1H NMR,FFIR,MS techniques and elemental analyses.The aggregation behavior of Zn（OAc）2 and the ligands 4a～4c in solution was investigated by UV-vis.The luminescence properties of compounds 5a～5c were investigated by fluorescence spectra in solid and DMF solution at room temperature.The results showed that the λmaxof compounds 5a～5c were 596,625 and 592 nm in solid,and were 562,536 and 618 nm in DMF solution.The comparative study of the luminescent properties of 5a～5c showed that the emission λmax can be tuned by introducing nitro groups at different positions of benzene.
