摘　　要：金属-有机配位聚合物是近年来配位化学和晶体工程学研究的焦点,其结构的多样性以及在气体吸附、催化、磁性、手性识别与分离、发光和生物学、非线性光学等方面潜在的应用价值引起了化学界的广泛关注。配位聚合物一般是指金属离子与小分子配体通过自组装过程形成的,具有周期性网络结构的金属有机骨架材料。金属-有机骨架晶体材料的制备以及配体的选择对结构性质具有重要影响,常见的合成方法有:蒸汽扩散法;高压釜法;溶剂缓慢挥发法;液相扩散法等。本课题以Cd金属作为中心离子,以5-(4-四氮唑基)-苯基间苯二甲酸为配体,使用高压釜法中的水热合成法,得到金属-有机配位聚合物。(简要描述两个化合物的结构)并将制备出来的晶体材料用X-射线粉末衍射、热重分析这些表征手段进行表征。Metal organic coordination polymers are the focus of coordination chemistry and crystal engineering in recent years.Their structural diversity and potential application value in gas adsorption,catalysis,magnetism,chiral recognition and separation,luminescence and biology,nonlinear optics and so on have attracted extensive attention in the chemical community.Coordination polymers generally refer to metal organic framework materials with periodic network structure formed by self-assembly of metal ions and small molecular ligands.The preparation of metal organic framework crystal materials and the selection of ligands have an important impact on the structural properties.The common synthesis methods are:vapor diffusion method;autoclave method;solvent slow volatilization method;liquid phase diffusion method,etc.In this paper,metal organic coordination polymers are obtained by hydrothermal synthesis in autoclave method with CD metal as central ion and 5-(4-tetrazolyl)-phenylisophthalic acid as ligand.(briefly describe the structures of the two compounds)and the prepared crystal materials are characterized by X-ray powder diffraction and thermogravimetric analysis.
