Abstract

A new strategy is successfully applied to "old" acetyl compounds. A free-standing, porous, N-doped carbonaceous membrane is facilely prepared from the thermal treatment of a pyrrole-ring-containing polymeric membrane based on the superacid-catalyzed copolymerization of acetyl monomers. An exceptional ideal CO₂/N₂ permselectivity of 43.2 is achieved with a good CO₂ permeability of 1149.3 Barrer, exceeding the recent upper bound for CO₂/N₂.
