南昌航空大学硕士学位论文 摘要测试其相匹配我们知道其最佳产生倍频效应的粒径大小分别为 100-125μm 和 300-400μm。化合物 5-6 是两个孤立的异质同构体，1，10-菲罗啉、H3CAM 于金 属离子同时配位。配位金属离子中心左右有机配体不同，破坏了其对称性。化合 物 7 中 H3CAM 未参加配位，由于均苯三甲酸的三个羧酸基团产生了不同的配位 模式，导致了结构的不对称。3. 多核的配位聚合物因利用具有不同的几何构型的金属离子，更容易产生 新颖的结构。化合物 8-9 分别为 1D 的铁道型和 2D 的方格配位聚合物，它们因 为阴离子的体积不同影响了其结构骨架，形成不同维数配位聚合物，化合物 10 是一个 3D 的多核 Cd(II)离子的配位聚合物，Cd 表现出了两种不同的几何构型。 总之，本文详细讨论了该类化合物的设计和组装的影响因素，并做了相关结 构表征和性能研究，总结了结构和性能的关系，为后续的深入研究提供了基础。关键词：白屈菜氨酸，配位聚合物，非心空间群，圆二色谱，光学性质AbstractThe purpose of design and assembly of coordination polymers is that organic ligand with specific functions and metal ions stack according to scheduled structure arrangement, which new compounds with expected structures and properties are obtained. Especially these new material in the optics, photoelectricity and magnetism, hydrogen storage, catalysis and chemical drug design has a large potential application value and the profound influence on search of new material. The designs and assemblies of coordination polymers have got particular attention, and different structures and properties of the compounds will be obtained under different experimental conditions, which become the big challenge for the chemists.The two similar Y organic ligands, 5-(3-Pyridyl)-isophthalic acid (PIA) and Chelidamic acid (H3CAM), were studied in this work. Ten novel coordination polymers were synthesized through the reaction of four auxiliary ligands of terephthalic acid, trimesic acid, 1,10-phenanthroline monohydrate and succinic acid with the transition metal ions, rare earth metal ions or mixed metal ions, respectively, by the hydrothermal or solution method. On the basis of the X-ray diffraction analysis of these complexes, compounds 1-2 have chiral space group, compounds 3-7 are noncertrosymmetric, and compounds of 8-10 are coenocytic. The characterizations of the element analysis, thermogravimetric analysis, UV spectra and infrared spectrum were done for the complexes. And CD spectra, nonlinear-optical properties and phase match
