Through a radical solvothermal polymerization method, we synthesized two porous organic polymers based on Tröger's base (POP‐TB and POP‐Me‐TB) from the corresponding vinyl‐functionalized monomers (2,8‐divinyl‐6 H ,12 H ‐5,11‐methanodibenzo[ b , f ]diazocine and 2,8‐divinyl‐4,10‐dimethly‐6 H ,12 H ‐5,11‐ethanodibenzo[ b , f ]diazocine; v‐TB and v‐Me‐TB). The structure and porosity of these polymers are verified by using solid‐state NMR spectroscopy, elemental analysis, SEM, TEM, N 2 sorption isotherms, and CO 2 sorption tests. They exhibit high surface areas and moderate pore volumes, which give high CO 2 adsorption capacities (90 and 71 mgCO2 g −1 at 273 K and 60 and 44 mgCO2 g −1 at 298 K for POP‐TB and POP‐Me‐TB, respectively) under a CO 2 pressure of 1 bar. In addition, they display excellent catalytic activities together with highly stability as heterogeneous catalysts in the benchmark Knoevenagel reactions.
