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