Three different monomers have been used to prepare novel Bergman cyclization-based porous organic polymers (BCPOPs). The synthesis route to BCPOPs is facile and highly-effecient. Meanwhile, BCPOPs show high physicochemical stability and excellent porosities. The Brunauer–Emmett–Teller specific surface area of BCPOPs is up to 860 m² g⁻¹, while the carbon dioxide uptake reaches to 11.1 wt% (1.0 bar and 273 K). Additionally, BCPOPs exhibit remarkable CO2/N2 selectivity and CO2/CH4 selectivity up to 38.6 (IAST at 273 K and 1.0 bar) and 9.6 (IAST at 273 K and 1.0 bar), respectively. By employing an easy and effective synthesis procedure, the obtained polymers are believed to be promising candidates for gas storage and separation.
