摘要
采用1,10-邻菲罗啉和均苯四甲酸为配体,以Zn(Ⅱ)为中心金属,通过水热法成功合成了配位聚合物[Zn(C_(10)H_(4)O_(8))(C_(12)H_(8)N_(2))H_(2)O].利用单晶X射线衍射技术对配合物的结构进行了详细表征:Zn(Ⅱ)为六配位,与3个均苯四甲酸、1个1,10-邻菲罗啉以及1个水分子配位;配合物通过分子间的氢键作用拓展为三维网状结构.通过配合物的紫外吸收光谱分析,发现配合物有更宽泛的可见光吸收范围.光致发光光谱证明,配合物的最大发射波长为400 nm.热重测试结果表明,配合物具有良好的热稳定性.
Using 1,10-phenanthroline and pyromellitic acid as ligands,and Zn(Ⅱ)as the central metal,a coordination polymer,[Zn(C_(10)H_(4)O_(8))(C_(12)H_(8)N_(2))H_(2)O],was successfully synthesized via a hydrothermal method.The structure of the coordination polymer was extensively characterized using single-crystal X-ray diffraction technique.The Zn^(2+) was six coordinated and connected to three pyromellitic acid,one 1,10-phenanthroline and one H_(2)O.The complex formed a three-dimensional network structure through intermolecular hydrogen bonding interactions.Analysis of the UV-visible absorption spectrum of the coordination polymer revealed a broader range of visible light absorption.Photoluminescence spectra indicated a maximum emission wavelength at 400 nm for the coordination polymer.Thermal gravimetric analysis results demonstrated the coordination polymer s excellent thermal stability.
