使用三种不同的单体制备了新型伯格曼环化多孔有机聚合物（BCPOPs）。BCPOP的合成路线简便、高效。同时，BCPOP具有较高的物理化学稳定性和优异的孔隙率。BCPOP的Brunauer-Emmett-Teller比表面积高达860 m2 g −1，而二氧化碳吸收率达到11.1 wt%（1.0 bar和273 K）。此外，BCPOP还具有显著的CO2/N2选择性和CO2/CH 4选择性，分别达到38.6（IAST，273 K，1.0 bar）和9.6（IAST，273 K，1.0 bar）。通过采用一个简单而有效的合成程序，所获得的聚合物被认为是有前途的候选人的气体储存和分离。
Three different monomers have been used to prepare novel Bergman cyclization-based porous organic polymers (BCPOPs). The synthesis route toBCPOPsis facile and highly-effecient. Meanwhile,BCPOPsshow high physicochemical stability and excellent porosities. The Brunauer–Emmett–Teller specific surface area ofBCPOPsis up to 860 m2g−1, while the carbon dioxide uptake reaches to 11.1 wt% (1.0 bar and 273 K). Additionally,BCPOPsexhibit remarkable CO2/N2selectivity and CO2/CH4selectivity 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.
