以4-(1-咪唑基)苯甲酸和桥联氯构筑的一维梯状结构的镉配位聚合物的晶体结构和荧光性质

摘要

The self-assembly of 4-(1H-Imidazol-1-yl)benzoic acid and CdCl2 under hydrothermal condition gave a new 1D cadmium coordination polymer,[Cd(imbz)(Cl)(H2O)]n (1) (imbz=4-(1H-Imidazol-1-yl)benzoate),which has been characterized by elemental analysis,IR,TGA and single-crystal X-ray diffraction.The imbz ligands link the Cd(Ⅱ) ions to form an infinite 1D zigzag chain,which the neighboring zigzag chains are further connected into a ladder chain through μ2-Cl ligands.The photoluminescence and lifetime of complex 1 in the solid state at room temperature have been studied.CCDC:890931.%水热条件下以CdCl2和4-(1-咪唑基)苯甲酸(Himbz)为反应物合成出一个新的具有一维梯子型链状结构的配位聚合物[Cd(imbz)(Cl)(H2O)n(1),并分别用元素分析,红外谱图,差热分析和X-射线单晶衍射表征该结构.晶体结构分析结果表明:4-(1-咪唑基)苯甲酸离子(imbz)将Cd(Ⅱ)离子连接成一维Z字链,进而通过桥联氯原子被连接成一维梯状链结构,荧光谱图表明常温固态下配合物1发射蓝色荧光,荧光寿命为2.21 ns.
