摘要

Two microporous metal-organic frameworks, Zn-2(HDDCBA)center dot 2DMF center dot 2H(2)O (1) and Cd-2(DDCBA)center dot DMA center dot H2Ocenter dot H2N(Me)(2) (2) have been synthesized under solvothermal condition by using a less-exploited symmetrical pentacarboxylate ligand, 3,5-di(3', 5'-dicarboxylphenyl)benozoic acid (H5L). Both compounds 1 and 2 reveal the (5,5)-connected nets based on the binuclear metal clusters and organic linkers. The desolvated structure of 1 (1a) contains two shapes of 1D channel with suitable pore size and polar system decorated by uncoordinated carboxylate groups. As a result, 1a possesses not only high CO2 loading but also excellent CO2/CH4 selectivity at 273 and 298 K. In addition, both compounds display solid-state luminescence stemming from the ligand-centered fluorescence of H5L.
