摘要
The novel supramolecular frameworks [Cd(BDC)(phen)(H2O)1,, (2) and [Cd-2(HBTC)(2)(phen)(2)](2n)Cd-.(HBTC)(phen)2 (3) have been synthesized by reaction of the metal source Cd(phen)(2)(NO3)(2) (1) with benzene-1,4-dicarboxylic acid (H2BDC) and benzene-1,3,5-tricarboxylic acid (H3BTC), respectively in a mixed solution of DMF/C2H5OH/H2O. The three-dimensional supramolecular structure of 2 is constructed through hydrogen-bond and aromatic pi-pi interactions between adjacent metal-organic polymeric coordination chains. Conversely, interestingly, the supramolecular architecture 3 is formed by extending 1-D metal-organic polymeric coordination chains into a 3-D framework by hydrogen-bond interactions between polymeric coordination chains and metal-organic coordination complexes instead of by interchain hydrogen-bond interactions. Additionally, these three compounds exhibit strong fluorescence at room temperature in the solid state.
