Abstract

Graphical abstract: A novel Cd(II) MOF with fascinating double-walled structure was synthesized under solvothermal condition. The luminescence investigation indicating that the MOF can act as a luminescent sensor for highly selective and sensitive sensing of Cr2 O7 2− anion. Abstract: A novel Cd(II) metal–organic framework, [Cd3 L3 (DMF)2 ] n (1 ), was synthesized using 5-(1H-1, 2, 4-triazol-1-yl)isophthalic acid (H2 L) and Cd(NO3 )2 ·6H2 O under solvothermal condition. The structure of 1 was characterized by X-ray crystallography, elemental analysis, and IR spectrum. Compound 1 possessed a fascinating three-dimensional (3D) double-walled framework with one-dimensional (1D) channels. The luminescence properties of compound 1 toward anion detection were systematically investigated. The results indicate that compound 1 behaves as a highly selective and sensitive 'turn-off' luminescence probe toward Cr2 O7 2− anion.
