The tetracationic macrocycle cyclo[2](2,6-di(1H-imidazol-1-yl)pyridine)[2](1,4-dimethylene-benzene) (1 4+ ) acts as a large, flexible ‘molecular box’ binding linear n-aliphate dianion (from oxalate dianion (2) to sebacate dianion (10)) with 1:1 stoichiometry and ‘outside’ binding modes in DMSO-d 6. In solid state, 1 4+ constructs a series of supramolecular organic frameworks (SOFs) with these anionic direction. Initial study of SOF-10 (the SOF structure formed from 1 4+ and sebacate dianion (10)) show highly selective CO2 absorption ability over N2.

“得克萨斯大小”分子盒与线性正α-脂族双阴离子之间的络合:进入超分子有机骨架(SOF)以选择性吸收CO2

四阳离子大环环[2](2,6-二(1H-咪唑-1-基)吡啶)[2](1,4-二亚甲基苯)(1 4+)充当一个大的柔性分子盒”以1:1的化学计量比和DMSO-d 6中的“外部”结合模式结合线性n-aliphate二价阴离子(从草酸二价离子(2)到癸二酸二价离子(10))。在固态下,1 4+会按照这些阴离子方向构建一系列超分子有机骨架(SOF)。对SOF-10(由1 4+和癸二酸二价阴离子(10)形成的SOF结构)的初步研究显示出对N 2的高选择性CO 2吸收能力。
