通过水热方法 ,采用H3pimda(2-propyl-1H-imidazole-4,5-dicarboxylic acid)与CdSO4.8/3H2O和Nd2O3反应,合成了1个具有一维孔道的配位聚合物[Cd(H2pimda)2]n(1),并对其结构和荧光性质进行了研究。结构分析结果表明该聚合物的晶体属于单斜晶系,P21/n空间群。4个H2pimda-配体桥联4个镉(Ⅱ)离子形成了1个方环,这些环通过镉(Ⅱ)离子与H2pimda-配体的配位作用形成了1个具有一维孔道的三维框架结构。值得关注的是配合物1的晶体呈现一种微米管的外型。研究表明,该聚合物中在室温下能发出很强的兰色荧光。
A 1-dimensional coordination polymer [Cd (H2pimda) was synthesized by the hydrothermal method using H3pimda (2-propyl-1H-imidazole-4,5-dicarboxylic acid) with CdSO4.8 / 3H2O and Nd2O3 ) 2] n (1), and its structure and fluorescence properties were studied. The structural analysis results show that the crystal of the polymer belongs to the monoclinic space group P21 / n. Four H2pimda-ligands bridged four cadmium (Ⅱ) ions to form a square ring. These rings formed a three-dimensional framework with one-dimensional pore channels through coordination between cadmium (Ⅱ) ions and H2pimda-ligand structure. It is noteworthy that the crystal of complex 1 presents the appearance of a kind of microtube. Studies have shown that the polymer emits a strong blue fluorescence at room temperature.
