摘要: A crystalline and permanently porous copper phosphonate monoester framework has been synthesized from a tetraaryl trigonal linker. This material surface area over 1000 m2 g−1, as measured by N2 sorption, the highest reported for phosphonate-based metal–organic (MOF). The monoesters result in hydrophobic pore surfaces that give low heat of adsorption CO2 calculated selectivity CH4 binary mixtures. By careful manipulation synthetic conditions, it is possible to selectively remove some lining form hydrogen while giving an isomorphous structure. increases affinity higher ambient uptake, adsorption, much both CH4. Formation acid groups noteworthy complexation with parent gives different
