Synthesis of tunable porosity of fluorine-enriched porous organic polymer materials with excellent CO₂, CH₄ and iodine adsorption.

ABSTRACT: 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 CO₂ of 5.35 mmol g^-1 at 273 K, and 4.18 mmol g^-1 at 298 K, which is higher than the reported values for most porous polymers. In addition, FCMP-600@1-4 display high selectivity of CO₂/N₂ and high CH₄ uptakes.
