Two mesoporous fluorinated metal-organic frameworks (MOFs) were synthesized from extensively fluorinated tritopic carboxylate- and tetrazolate-based ligands. The tetrazolate-based framework MOFF-5 has an accessible surface area of 2445 m(2) g(-1), the highest among fluorinated MOFs. Crystals of MOFF-5 adsorb hydrocarbons, fluorocarbons, and chlorofluorocarbons (CFCs)-the latter two being ozone-depleting substances and potent greenhouse species-with weight capacities of up to 225%. The material exhibits an apparent preference for the adsorption of non-spherical molecules, binding unusually low amounts of both tetrafluoromethane and sulfur hexafluoride.
两种介孔氟化金属-有机骨架（MOF）是由广泛氟化的三齿羧酸酯和四唑基配体合成的。基于四唑的骨架 MOFF-5 的比表面积为 2445 m2/g，是所有氟化 MOF 中最高的。MOFF-5 的晶体吸附烃类、氟碳化合物和氯氟碳化合物（CFCs）——后两者是消耗臭氧层物质和强效温室气体——其重量容量高达 225%。该材料对非球形分子的吸附表现出明显的偏好，对四氟甲烷和六氟化硫的吸附量都异常低。
