摘要

Two isostructu ral Ni(Ⅱ)/Co(Ⅱ)-based metal-organic frameworks(MOFs),namely {[M3(L)2(bpb)3(H2 O)4]·2 DMF·2 H2 O}n [M=Ni(HL-5,HL is short for Hui-Ling Liu);M=Co(HL-6);H3 L=2’,6’-dimethyl-[1,1’-biphenyl]-3,4’,5-tricarboxylic acid;bpb=1,4-bis(pyrid-4-yl)benzene],have been hydrothermally synthesized and structu rally characterized.Both HL-5 and HL-6,which have the same three-interpenetrated3 D pillared-layer framework with sqc306 type topology,present good selective methyl orange(MO)adsorption over rhodamine B(RhB).Moreover,the catalytic CO2 cycloaddition properties with epoxides of the two MOFs have also been studied at ambient pressure and temperature.
