A Cd-containing metal-organic framework (CdL), formula as {[Cd-3(L)(2)(H2O)(6)]center dot 1.5DMF}, has been synthesized under solvothermal condition by the reaction of 4,4',4 ''-(methylsilanetriyl)tribenzoic acid (H3L) and Cd2+. ion. Single-crystal X-ray diffraction reveals that CdL 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 CdL is a 3,4-connected pto net. The photoluminescence properties of CdL are systematically studied in detail. Impressively, CdL shows excellent detection performance towards Fe3+ ion and acetone in the sensing experiments, which undoubtedly demonstrates the great potential of CdL as a highly selective multi-responsive luminescent sensor for the detection of organic solvents and metal ions.
