CO(2) Separation by Imide/Imine Organic Cages

Two novel imide/imine‐based organic cages have been prepared and studied as materials for the selective separation of CO(2) from N(2) and CH(4) under vacuum swing adsorption conditions. Gas adsorption on the new compounds showed selectivity for CO(2) over N(2) and CH(4). The cages were also tested a...

Descripción
Sumario:Two novel imide/imine‐based organic cages have been prepared and studied as materials for the selective separation of CO(2) from N(2) and CH(4) under vacuum swing adsorption conditions. Gas adsorption on the new compounds showed selectivity for CO(2) over N(2) and CH(4). 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(2) were achieved compared to the neat polymer membranes.
