摘　　要：制备了配位聚合物2-吡啶甲酸铜{[CuL2]·2H2O}n(HL=2-吡啶甲酸).通过元素分析、红外光谱、X-射线单晶衍射等方法对配位聚合物结构进行了表征.采用紫外-可见光谱和荧光光谱研究了配位聚合物在DMF溶液中的发光性能.结果表明,目标配位聚合物具有良好的光学性质,温度对在272nm的吸光度值和346nm处的荧光发射强度有重要影响.同时循环伏安曲线显示标题配位聚合物的氧化还原过程较困难,电化学性质稳定性.The ligand of 2-Pyridinecarboxylic acid （HL） and its metal complex of {[CuL2]·2H2O}. have been synthesized and characterized by elemental analysis, IR, and single crystal X-ray diffraction methods. The irradiance behavior of the complex was studied in solvent of DMF by UV-vis and fluo- rescent spectra. The results indicate that compound has perfect optical property. The absorption at 272 nm and fluorescence intensity at 346 nm of the complex exhibit linear relationship with tempera- ture. Electrochemical properties show title complex REDOX more difficult, stability is good.
