    Abstract

    A nanopore engineering approach enhances acetylene (C 2 H 2 ) over carbon dioxide (CO 2 ) selectivity in ionic ultramicroporous polymers (IUPs), an understudied class of sorbents. Extending the cationic arm of a prototypical IUP nearly doubles its C 2 H 2 /CO 2 selectivity from 4.9 to 8.5 (at 298 K, 1 bar), underpinned by further observations from dynamic separation experiments and bespoke computational insights.
