A multi-responsive luminescent sensor towards Fe3+ and acetone based on a Cd-containing metal–organic framework

A Cd-containing metal–organic framework(Cd L), formula as {[Cd3(L)2(H2O)6] 1.5DMF}, has been synthesized under solvothermal condition by the reaction of 4,40,400-(methylsilanetriyl)tribenzoic acid(H3L) and Cd2+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 L is a 3,4-connected pto net. The photoluminescence properties of Cd L are systematically studied in detail. Impressively, Cd L shows excellent detection performance towards Fe3+ion and acetone in the sensing experiments, which undoubtedly demonstrates the great potential of Cd Lasa highly selective multi-responsive luminescent sensor for the detection of organic solvents and metal ions.
