通过水热方法,采用H3IDC(H3IDC=imidazole-4,5-dicarboxylicacid)、prz(prz=piperazine)与Cd(NO3)2·4H2O反应,合成了具有一维孔道的配位聚合物[{NaCd4(IDC)3(prz)}·3H2O]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化合物属于单斜晶系,Cc空间群。其结构单元中含有4个独立的Cd原子。3个Cd原子形成一个小环,6个Cd原子形成一个大环。这些环通过IDC3-和Cd(Ⅱ)的配位作用,进一步连接产生了含一维孔道的配位聚合物。孔道内含有大量水分子和Na+离子。研究表明,该配合物在室温下能发出很强的兰色荧光。 The coordination polymer [{NaCd4 (superscript +)] with one-dimensional pore was synthesized by hydrothermal method using H3IDC (imidazole-4,5-dicarboxylic acid) and prz IDC) 3 (prz)} · 3H2O] n (1), and its structure and fluorescence properties were studied. The structural analysis results show that the compound belongs to the monoclinic Cc space group. Its structural unit contains four independent Cd atoms. Three Cd atoms form a small ring, six Cd atoms form a large ring. These rings are coordinated by IDC3- and Cd (II) to form a coordination polymer containing one-dimensional pores. Hole contains a large number of water molecules and Na + ions. Studies have shown that the complex emits strong blue fluorescence at room temperature.
