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‐6H,12H‐5,11‐methanodibenzo[b,f]diazocine and 2,8‐divinyl‐4,10‐dimethly‐6H,12H‐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, N2 sorption isotherms, and CO2 sorption tests. They exhibit high surface areas and moderate pore volumes, which give high CO2 adsorption capacities (90 and 71 mgurn:x-wiley:18673880:media:cctc201701534:cctc201701534-math-0001 g−1 at 273 K and 60 and 44 mgurn:x-wiley:18673880:media:cctc201701534:cctc201701534-math-0002 g−1 at 298 K for POP‐TB and POP‐Me‐TB, respectively) under a CO2 pressure of 1 bar. In addition, they display excellent catalytic activities together with highly stability as heterogeneous catalysts in the benchmark Knoevenagel reactions.
