摘　　要：本文利用水热合成法,合成得到了一种基于磷钨杂多酸(H_(3)PW_(12)O_(40))的银离子配位聚合物材料([Ag_(2)(BPBP)_(3)PW_(12)O_(40)]).单晶X-射线衍射分析表明:银离子连接有机配体形成一维链状结构,而多酸通过Ag-O键位于链的一侧,最终链状结构通过氢键等超分子作用链接成三维超分子结构.本文利用复合改性玻碳电极(GCE)作为工作电极,研究了材料的电化学性能.此外,本文还研究了材料的热稳定性.In this work,a silver ion coordination polymer material([Ag_(2)(BPBP)_(3)PW_(12)O_(40)]),based on phosphotungstic heteropolyacid(H_(3)PW_(12)O_(40))was synthsised by hydrothermal method.Single crystal X-ray diffraction analysis showed that silver ion was connected with organic ligand to form a one-dimensional chain,while Ag-O bonds linked POMs which located on one side of the chain.The chains form to final three-dimensional structure through supramolecular interactions such as hydrogen bonds.We used carbon electrode(GCE)as the working electrode, and investigated the electrochemical properties of the material.Meanwhile,we studied the thermal stability of the material.
