摘要
The synthesis of crystalline polyphenylene covalent organic frameworks (COFs) was accomplished by linking fluorinated tris(4-acetylphenyl)benzene building units using aldol cyclotrimerization. The structures of two COFs, reported here, were confirmed by powder X-ray diffraction techniques, Fourier-transform infrared, and solid-state 13C CP/MAS NMR spectroscopy. The results showed that the COFs were porous and chemically stable in corrosive, harsh environments for at least 1 week. Accordingly, post-synthetically modified derivatives of these COFs using primary amines showed CO2 uptake from air and flue gas.
