We herein report the construction of four the novel fluorine-enriched conjugated microporous polymers (FCMP-600@1-4), which have permanent porous structures and plenty of fluorine atoms in the skeletons as effective sorption sites. Among them, FCMP-600@4 shows considerable adsorption capacity of CO of 5.35 mmol g at 273 K, and 4.18 mmol g at 298 K, which is higher than the reported values for most porous polymers. In addition, FCMP-600@1-4 display high selectivity of CO/N and high CH uptakes.
我们在此报告了四种新型富氟共轭微孔聚合物（FCMP - 600@1 - 4）的构建，它们具有永久多孔结构，且骨架中有大量氟原子作为有效的吸附位点。其中，FCMP - 600@4在273 K时对CO的吸附容量为5.35 mmol g，在298 K时为4.18 mmol g，高于大多数多孔聚合物的报道值。此外，FCMP - 600@1 - 4对CO/N表现出高选择性和对CH的高吸附量。
