The emission of SO 2 from the burning of fossil fuel has resulted in a severe atmospheric pollution. The development of efficient strategies for not only capturing but also utilizing SO 2 is highly welcome. A simple, mild, and versatile method has been developed that exploits atmospheric SO 2 in the synthesis of porous polymers. Inspired by the chemistry of sulfonamides, contorted or bulky monomers with multiple amine groups were cross‐linked by SO 2 molecules in the presence of Et 3 N and I 2 . The sulfonamide polymers have specific surface areas up to 211 m 2 g −1 . In contrast to most porous polymers, the porous sulfonamide polymers (PSPs) are soluble in organic solvents, thus offering a chance to study their structures and molecular weights by liquid‐state NMR spectroscopy and gel‐permeation chromatography, respectively. Moreover, these PSPs can be easily processed into organic membranes. The current concept should encourage more studies to design porous polymers with SO 2 or CO 2 gases as linkages.
