Metal-organic frameworks (MOFs) have attracted great attention in the past years due to their diverse structures as well as interesting properties. However, MOFs with multifunctionality are still challenging. Under solvotherMal conditions, reactions of 1,3,5-tris(1-imidazolyl)benzene (tib) and 4,4',4-benzene-1,3,5-triyl-tribenzoic acid (H3BTB) with Cd(II) salt give rise to two novel MOFs [Cd-3(tib)(2)(BTB)(2)]center dot 3DEF center dot 4.5H(2)O (1) and [Cd-3(tib)(2)(BTB)(2)(DMA)(2)(H2O)(2)]center dot 2DMA center dot 8H(2)O (2) (DEF = N,N-diethylformamide, DMA = N,N-dimethylacetamide) with three-dimensional framework structures. It is fascinating that 1 and 2 not only show unique selectivity for detection of acetone through fluorescence quenching mechanism but also exhibit selective adsorption of gas (CO2 over N-2 at 298 K) and dye (methyl orange) molecules.
