摘要：One novel metal-organic framework (MOF),[Ba(L)(H2O)1.5]n (1,H2L = aniline-2,5-disulfonic acid),has been synthesized by hydrothermal method.Each barium atom is eleven-coordinated into a distorted monocapped Pentagonal antiprismatic arrangement.Compound 1 shows an interesting 3D pillar-layered structure constructed from 2D inorganic layers [Ba(SO3)2(H2O)1.5]n and organic pillars of phenyl moieties of L^2-linkages.The inorganic layers are supported by the organic pillars,generating a novel 3D open framework structure with {3,46,55,65, 74}2{3}{5}topology.The result of fluorescence measurement can reveal that the decayed emission band centered at 492nm may be caused by the interactions of the ligands and the metal ions. Compound 1 exhibits selective toward the adsorption of CO2 over N2at 273K.
