A luminescent metal-organic framework, [Cd-2(TBA)(2)(bipy)(DMA)(2)] (1), has been synthesized under solvothermal conditions by employing mixed ligands of 4-(1H-tetrazol-5-yl)-benzoic acid (H(2)TBA) and 4,4'-bipyridine (bipy). Structure analysis shows that compound 1 is a three-dimensional network with a new (3,4,4)-connected topology. Compound 1 possesses the advantages of good water stability and exceptional thermal stability; it can retain framework crystallinity when it was suspended in water vapor for 10 hours or heated in air at 320 degrees C. Interestingly, when compound 1 detected different volatile organic solvent molecules, the variation of luminescence intensity depends on the various organic solvents and acetone shows the best quenching behavior. The results indicate that compound 1 may be considered as a potential luminescent probe for the detection of acetone.
