摘要
A Cd-containing metal–organic framework(Cd L), formula as {[Cd_3(L)_2(H_2O)_6] 1.5DMF}, has been synthesized under solvothermal condition by the reaction of 4,40,400-(methylsilanetriyl)tribenzoic acid(H_3L) and Cd^(2+)ion. Single-crystal X-ray diffraction reveals that Cd L displays a three-dimensional framework with 2-fold interpenetration and DMF molecules locate in the void space of the channels. A topological analysis of the framework indicates Cd Lisa 3,4-connected pto net. The photoluminescence properties of Cd L are systematically studied in detail. Impressively, Cd L shows excellent detection performance towards Fe^(3+)ion and acetone in the sensing experiments, which undoubtedly demonstrates the great potential of Cd L as a highly selective multi-responsive luminescent sensor for the detection of organic solvents and metal ions.
