文摘

Four crystalline, porous metal鈥搊rganic frameworks (MOFs), based on a new hexatopic linker, 1鈥?2鈥?3鈥?4鈥?5鈥?6鈥?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.
