Abstract
A novel NbO type microporous metal–organic framework [Cu2(C26H12O8)(H2O)2]·(DMF)2·(MeCN)3·(H2O)4, (ZJU-7, ZJU = Zhejiang University; H4L = 5,5′-(naphthalene-1,4-diyl)diisophthalic acid; DMF = N,N-dimethylformamide; MeCN = acetonitrile) has been synthesized and structurally characterized. With open metal sites, suitable pore spaces and moderately high permanent porosity, the activated ZJU-7a exhibits moderately high CH4 storage of 160 cm3(STP) per cm3 at 35 bar and 298 K. Meanwhile, ZJU-7a also displays moderate C2H2 gravimetric storage of 180 cm3 g−1 at 1 atm and 298 K.
