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.

Abstract
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.File in questo prodotto:
