通过水热方法 ,采用3-羧基苯氧乙酸(3-H2CPOA=3-carboxyphenoxyacetatic acid)和phen(phen=1,10-phenanthroline)与Cd(OAc)2.2H2O反应,合成了一个具有一维双链结构的配位聚合物[Cd(3-CPOA)(phen)]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,C2空间群。2个镉(Ⅱ)离子、2个3-CPOA2-配体和2个phen配体形成了1个[Cd2(3-CPOA)2(phen)2]环,这些环通过镉(Ⅱ)离子与3-CPOA2-配体的配位作用形成了1个一维双链结构。链与链之间又通过C-H…O氢键作用形成了1个三维的配位框架。研究表明,该聚合物在室温下能发出很强的蓝色荧光。
Through the hydrothermal method, 3-carboxyphenoxyacetatic acid (3-H2CPOA = 3-carboxyphenoxyacetatic acid) and phen (phen = 1,10-phenanthroline) were reacted with Cd (OAc) Structure of the coordination polymer [Cd (3-CPOA) (phen)] n (1), and its structure and fluorescence properties were studied. Structural analysis results show that the crystal of the polymer belongs to monoclinic system, space group C2. One Cd2 (3-CPOA) 2 (phen) 2] ring was formed by two cadmium (Ⅱ) ions, two 3-CPOA2-ligands and two phen ligands. The coordination of 3-CPOA2-ligands formed a one-dimensional double-stranded structure. Between the chain and the chain through the C-H ... O hydrogen bond formed a three-dimensional coordination framework. Studies have shown that the polymer emits very strong blue fluorescence at room temperature.
