文摘

A Cd-containing metal–organic framework (CdL), formula as {[Cd₃(L)₂(H₂O)₆]·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.
