IAST calculations reveal that sulfonate ammonium salt grafting renders porous polymer networks (PPN-6-SO3NH4) with exceptionally high adsorption selectivity for CO2 over N2 and CO 2 over CH4. Breakthrough experiments confirm the high CO2 adsorption capacity (1.7 mmol g-1, 75 mg g -1) by feeding 15% CO2 balanced with N2 at 295 K and 1 bar. © 2013 The Royal Society of Chemistry.
