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 CO 2 /N 2 permselectivity of 43.2 is achieved with a good CO 2 permeability of 1149.3 Barrer, exceeding the recent upper bound for CO 2 /N 2 .
