Abstract

Abstract: The conceptual, bottom‐up design of functional carbon materials from microporous organic polymers was investigated. Owing to their structural rigidity and synthetic flexibility, the porous polymers streamlined the thermal carbonization process while excluding the need for exogenous additives or extra synthesis procedures and allowed for simultaneous elemental engineering of the resultant carbonaceous materials. As designed, heteroatoms such as nitrogen and sulfur could be uniformly incorporated into the carbon matrices from the microporous polymers during thermal carbonization with a concomitant change in the macroscopic properties of the materials. In particular, doping with sulfur atoms could provide reactive sites, thereby conferring superior catalytic performance to the carbon materials. This study demonstrates expansion of the capability of microporous polymers as a functional carbon source and advances the synthetic concept for carbonaceous materials. Abstract : A bottom‐up design of carbons : Microporous organic polymers are demonstrated as a functional carbon precursor since they are able to facilely cause elemental engineering of carbon materials. As designed, doped heteroatoms provide active sites, and carbonaceous materials show catalytic performance as a heterogeneous catalysts.
