Solvothermal synthesis afford two new porous metal-organic frameworks (MOFs):
{[Cu6(L)3(H2O)4(py)2]•6(DMF)13(H2O)}n (1) and {[Cu6(L)3(H2O)6]•29(H2O}n (2).
[5,5’-(1,3-phenylenebis(methylene))bis(oxy)diisophthalic acid (HL)].
Although possessing similar structures, the two MOFs have markedly different stabilities.
Compound 1 and 2 can take up 16.8 mg/g and 15.9 mg/g of H2 at 77 K at 1 bar and 133 cm3/g and 120 cm3/g of H2 at 87 K (Fig. 8),
which is higher than the performance of well-known MOFs PCN-6 and HKUST-1 at 77 K and 1 bar.
Notably, both MOFs exhibited highly efficient, selective adsorption of CO2 over CH4 under ambient conditions.
Such compounds may therefore prove useful for gas separation and purification.
