As a C 1 feedstock, CO 2 has the potential to be uniquely highly economical in both a chemical and a financial sense. Porous materials bearing particular binding and active sites that can capture and convert CO 2 simultaneously are promising candidates for CO 2 utilization. In this work, a bipyridine‐constructed polymer featuring a high surface area, a hierarchical porous structure, and excellent stability was synthesized through free‐radical polymerization. After metalation, the resultant catalysts exhibited superior activities in comparison with those of their homogeneous counterparts in the cycloaddition of CO 2 to epoxides. The high performance of the heterogeneous catalysts originates from cooperative effects between the CO 2 ‐philic polymer and the embedded metal species. In addition, the catalysts showed excellent stabilities and are readily recyclable; thus, they are promising for practical utilization for the conversion of CO 2 into value‐added chemicals.
