摘　　要：功能配位聚合物的合成及性能研究,为开发配位聚合物的光致发光和电致发光材料奠定基础。间苯二乙酸、4,4'-二(咪唑基-1-亚甲基)联苯和氯化铅在水热条件下合成配合物[Pb(Hmpda)(bibp)Cl]·H_2O(Hmpda=间苯二乙酸,bibp=4,4'-二(咪唑基-1-亚甲基)联苯)。利用x射线测得晶体结构,同时红外光谱、元素分析、荧光分析等手段对晶体配合物进行了表征。该配合物中,bibp连接[Pb_2Cl_2]^(2+)结构单元,形成一维聚合链,一维链之间通过bibp的连接构成二维结构,若将[Pb_2Cl_2]^(2+)单元作为结构点,该二维结构就是典型的(4,4)网格,二维结构又以ABAB的形式堆叠形成三维结构。另外,还研究了配合物的荧光性能,发现加入金属Pb^(2+)使间苯二乙酸的荧光强度变弱,同时发生了红移,渴望将这一性能应用于测定药品、生物样品、有机分子和无机离子等。Synthesis and property of the function coordination polymer were reviewed,which will lay a foundation for the development of photoluminescence and electroluminescence of coordination polymer.[Pb(Hmpda)(bibp)Cl]·H 2O(Hmpda=m-phenylenediacetate,bibp=4,4′-bis(imidazolyl-1-methylene)biphenyl),has been synthesized by hydrothermal reactions.[Pb(Hmpda)(bibp)Cl]·H 2O was characterized by IR,fluorescent spectrum and single-crystal X-ray diffraction techniques.In this compound,bibp is connected to[Pb2Cl2]2+structural units to form one-dimensional polymer chains.The two-dimensional structure is formed by the connection of bibp between one-dimensional chains.If[Pb 2Cl2]2+units are used as structural sites,the dimensional structure is a typical(4,4)grid,two-dimensional structures in the form of ABAB stack to form a three-dimensional structure.In addition,we also studied fluorescent properties of the compound,fluorescence intensity of Hmpda is weak and red shift because of metals Pb 2+joining.It is desired to apply this performance to the determination of drugs,biological samples,organic molecules and inorganic ions.
