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 m(2) g(-1), while the carbon dioxide uptake reaches to 11.1 wt% (1.0 bar and 273 K). Additionally, BCPOPs exhibit remarkable CO2/N-2 selectivity and CO2/CH4 selectivity up to 38.6 (LAST at 273 K and 1.0 bar) and 9.6 (LAST 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. (C) 2017 Elsevier Ltd. All rights reserved.
