Effective carbon dioxide (CO2) capture requires solid, porous sorbents with chemically and thermally stable frameworks. Herein, we report two new carbon-carbon bonded porous networks that were synthesized through metal-free Knoevenagel nitrile-aldol condensation, namely the covalent organic polymer, COP-156 and 157. COP-156, due to high specific surface area (650 m2/g) and easily interchangeable nitrile groups, was modified post-synthetically into free amine- or amidoxime-containing networks. The modified COP-156-amine showed fast and increased CO2 uptake under simulated moist flue gas conditions compared to the starting network and usual industrial CO2 solvents, reaching up to 7.8 wt % uptake at 40°C.

The ruthenium-catalyzed Knoevenagel reaction was developed for the preparation of cyano-substituted conjugated polymers. The polymerization was quenched by pouring the reaction mixture into methanol. The structures of polymers were confirmed by spectroscopic studies and elemental analysis. The results show that Knoevenagel polycondensation mediated by transition metal complexes enjoys the advantages of neutral and mild reaction conditions.
