以Cd（NO3）2·6 H2O和5-（1H-1，2，4-三唑-1-基）烟酸（H2 L）为原料，在溶剂热条件下合成了一种新型的Cd（II）金属有机骨架化合物[Cd 3L 3（DMF）2]n（1）。通过X射线单晶衍射、元素分析和红外光谱对化合物1的结构进行了表征。化合物1具有迷人的三维（3D）双壁框架和一维（1D）通道。系统研究了化合物1对阴离子的荧光性质。结果表明，化合物1对Cr2 O 72 −阴离子具有高选择性和高灵敏度的“关断型”荧光探针.
A novel Cd(II) metal–organic framework, [Cd3L3(DMF)2]n(1), was synthesized using 5-(1H-1,2,4-triazol-1-yl)isophthalic acid (H2L) and Cd(NO3)2·6H2O under solvothermal condition. The structure of1was characterized by X-ray crystallography, elemental analysis, and IR spectrum. Compound1possessed a fascinating three-dimensional (3D) double-walled framework with one-dimensional (1D) channels. The luminescence properties of compound1toward anion detection were systematically investigated. The results indicate that compound1behaves as a highly selective and sensitive ‘turn-off’ luminescence probe toward Cr2O72−anion.
