Abstract

Four crystalline, porous metal-organic frameworks (MOFs), based on a new hexatopic linker, 1',2',3',4',5',6'-hexakis(4-carboxyphenyl)benzene (H6CPB), were synthesized and fully characterized. Interestingly, two members of this series exhibited new topologies, namely, htp and hhp, which were previously unseen in MOF chemistry. Gas adsorption measurements revealed that all members exhibited high CO2 selectivity over N2 and CH4. Accordingly, breakthrough measurements were performed on a representative example, in which the effective separation of CO2 from binary mixtures containing either N2 or CH4 was demonstrated without any loss in performance over three consecutive cycles.
