摘要：

Based on a new V-shaped tetracarboxylic ligand with a methoxyl group, a new mfj-type microporous metal-organic framework [Cu-6(MBDPB)(3)(H2O)(6)].12DMF.10H(2)O (NJFU-3, NJFU for Nanjing Forestry University; H4MBDPB for 5-methoxyl-1,3-bis(3,5-dicarboxylphenyl)-benzene) was successfully synthesized and structurally characterized. With moderately high porosity, appropriate pore aperture and unsaturated metal sites, the activated NJFU-3a exhibits high H-2 (2.56 wt% at 77 K and 1 bar) and CO2 uptakes (15.8 wt% at 298 K and 1 bar), and a moderately high CH4 storage capacity of 155 cm(3) cm(-3) at 35 bar and 298 K. Meanwhile, it shows a comparably high delivery amount of 135 cm(3) cm(-3) when taking 5 bar as a specific lower pressure limit and 65 bar as the upper limit.
