| 摘 要： | 在溶剂热条件下，合成了2个碱土金属配位聚合物Ca（tdc）（DMF）2]n（1）和Ba（tdc）]n（2）（H2tdc=2，5-噻吩二甲酸），分别用元素分析、红外光谱、X射线单晶衍射、粉末衍射、热重分析和荧光光谱对它们进行了表征。结构分析表明，配合物1具有4，4连接的二维层状结构，拓扑符号为（44·62），而配合物2呈现三维网络结构。固体荧光测试表明配合物1比配合物2具有更显著的荧光性能。

| Abstract: | Two new alkaline earth metal coordination polymersCa (tdc)(DMF)2]n(1) andBa (tdc)]n(2)(H2tdc=2,5-thiophene dicarboxylate) have been synthesized under solvothermal condition.They were characterized by elemental analysis,IR spectroscopy,single crystal X-ray diffraction,powder X-ray diffraction,thermogravimetric analysis,and fluorescent analysis.Complex 1 exhibits a two-dimensional (2D) layer structure with a uninodal (4,4)-connected (44·62) topological type;whereas,complex 2 features a 3D framework consisting of elongated hexagonal channels.Solid-state photoluminescent properties indicate that complex 1 shows noticeable fluorescent emissions upon excitation in comparison to that of complex 2. |
