用水热技术合成了一维锯齿链状多酸-有机配位聚合物{[Cu(en)2(H2O)][Cu(en)2(H2O)-PWⅤ3WⅥ9O40Cu(en)2].9H2O}n,用元素分析、X射线单晶衍射、IR、UV-vis、FS、cv和TG-DTA对其进行了表征.聚合物由有机金属配阳离子[Cu(en)2]2+桥联两个相邻的Keggin结构杂多阴离子[PWV3WV9IO40]6-,构成了一维锯齿链状聚合物.荧光光谱研究发现,标题化合物具有较好的光致发光性.循环伏安测定表明,标题化合物阴离子在pH=1.0的水溶液中存在3步氧化还原过程.TG-DTA结果表明聚合物中杂多阴离子在596.4℃时发生了分解.
One-dimensional serrated chain polyacid-organic coordination polymer {[Cu (en) 2 (H2O)] [Cu (en) 2 (H2O) -PWV3WVI9O40Cu (en) 2] It was characterized by elemental analysis, single crystal X-ray diffraction, IR, UV-vis, FS, cv and TG-DTA.The polymer was bridged by two organic phases [Cu The ortho-Keggin structure heteropolyanion [PWV3WV9IO40] 6- formed a one-dimensional serrated chain polymer.The fluorescence spectra showed that the title compound had good photoluminescence.The cyclic voltammetry showed that the title compound anion was stable at pH = 1.0, there is a three-step redox process in aqueous solution.The results of TG-DTA showed that the heteropolyanion in the polymer decomposed at 596.4 ℃.
