中文摘要	solvothermal reaction of cd2+ ions and a hexavalent carboxylic acid (h6l) afforded a cd(ii) metal organic framework (cd-mof), namely {[cd-3(l)(h2o)(2)(dmf)(2)]center dot 5dmf}(n) (1). its structure consists of trinuclear cd-ii building units, which are further bridged by the carboxylic ligand, resulting in a 4,4-connected topological net (sra). by introducing a rigid n-donor ligand 1,4-bis(1-imidazolyl)benzene (dib), a new cd-mof (2) {[cd-3(l)(dib)]center dot 3h(2)o center dot 5dma}(n) was isolated, in which the coordinated sites of solvent molecules in 1 were completely replaced by dib. the resulting trinuclear cd-3 subunits are further bridged into a two-fold interpenetrating network with dma and water molecules located in the void space. the luminescent properties of the two microporous cd-mofs dispersed in different solvents have been investigated systematically, demonstrating unique selectivity for the detection of acetone via a fluorescence quenching mechanism. their luminescence intensities decreased to 50% at an acetone content of 0.3 vol% and were almost completely quenched at a concentration of 1.0 vol%, thus, they can be considered as excellent potential luminescent probes for the detection of acetone.
