摘要：
A fluorous metal-organic framework, FMOF-1, is obtained by reaction of Ag(I) with 3,5-bis(trifluoromethyl)-1,2,4-triazolate, giving rise to a neutral, hydrogen-free, extended 3D nanotubular porous framework consisting of tetranuclear clusters [Ag(4)TZ(6)] connected by three-coordinate Ag(I) centers. The fluoro-lined channels and cavities of the framework show hysteretic adsorption of H-2 with a volumetric capacity of 41 kg/m(3) at 77 K and 64 bar. The framework also exhibits very high adsorptions for O-2 and N-2 with volumetric uptake of similar to 550 and 400 kg/m(3) at 77 K even at very low pressures (< 10(-2) bar).
