Direct fluorine- and sulfur-targeted postsynthetic modification in a porous organic polymer-based ammonia adsorbent†

Abstract

Postsynthetic modification of porous organic polymers (POPs) facilitates their use to remove toxic gases, such as NH₃. This study conducted a fluorine- and sulfur-targeted postsynthetic modification of POPs to enhance their low-pressure NH₃ adsorption capacity. For the first time, F and S-targeted postsynthetic modification for NH₃ capture using porous adsorbents was demonstrated.
