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.
基于新型六齿连接体1',2',3',4',5',6'-六（4-羧基苯基）苯（H6CPB）合成了四种晶体多孔金属有机框架（MOF），并对其进行了全面表征。有趣的是，该系列中的两个成员呈现出新型拓扑结构，即htp和hhp，这在MOF化学中是前所未见的。气体吸附测量结果表明，所有成员对CO2的选择性均高于N2和CH4。因此，对一个代表性实例进行了突破测量，结果表明在连续三个循环中，能够有效从含有N2或CH4的二元混合物中分离出CO2，且性能无任何损失。
