Two novel imide/imine-based organic cages have been prepared and studied as materials for the selective separation of CO from N and CH under vacuum swing adsorption conditions. Gas adsorption on the new compounds showed selectivity for CO over N and CH . The cages were also tested as fillers in mixed-matrix membranes for gas separation. Dense and robust membranes were obtained by loading the cages in either Matrimid® or PEEK-WC polymers. Improved gas-transport properties and selectivity for CO were achieved compared to the neat polymer membranes.
已经制备并研究了两种新型的基于酰亚胺/亚胺的有机笼状物，作为在变压吸附条件下从氮气和甲烷中选择性分离一氧化碳的材料。在新化合物上的气体吸附显示出对一氧化碳的选择性高于氮气和甲烷。这些笼状物还作为气体分离混合基质膜中的填料进行了测试。通过将笼状物负载到Matrimid®或聚醚醚酮耐磨级（PEEK-WC）聚合物中，获得了致密且坚固的膜。与纯聚合物膜相比，实现了改善的气体传输性能和对一氧化碳的选择性。
