Abstract

A nanopore engineering approach enhances acetylene (C₂H₂) over carbon dioxide (CO₂) selectivity in ionic ultramicroporous polymers (IUPs), an understudied class of sorbents. Extending the cationic arm of a prototypical IUP nearly doubles its C₂H₂/CO₂ selectivity from 4.9 to 8.5 (at 298 K, 1 bar), underpinned by further observations from dynamic separation experiments and bespoke computational insights.
