通过羟醛环三聚反应将氟化三（4-乙酰基苯基）苯结构单元连接起来，合成了结晶聚亚苯基共价有机骨架（COFs）。本文报道的两种COF的结构通过粉末X射线衍射技术、傅里叶变换红外光谱和固态13 C CP/MAS NMR光谱进行了证实。结果表明，COF是多孔的，并且在腐蚀性恶劣环境中至少1周是化学稳定的。因此，使用伯胺的这些COF的合成后改性衍生物显示出从空气和烟道气中吸收CO2。
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 the 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, postsynthetically modified derivatives of these COFs using primary amines showed CO2 uptake from air and flue gas.
