Developing novel strategies for the construction of covalent organic frameworks (COFs) is always the focus of current research. Recently, the visible-light mediated photocatalysis has been introduced to produce COFs, due to its mild and green characteristics. However, there are still rare reports about the photocatalytic synthesis of COFs. Herein, a series of imine-linked COFs including TAPB-PDA-COF, TAPT-PDA-COF, TZ-BTCA-COF, and COF-LZU1 (TAPB, 1,3,5-tris-(4- aminophenyl)benzene; PDA, terephthalaldehyde; TAPT, 2,4,6-tris(4-aminophenyl)-1,3,5-triazine; TZ, 2,4,6-tris(4-amino- phenyl)-1,3,5-triazine; BTCA, 1,3,5-benzenetricarbaldehyde) were successfully synthesized via the photocatalytic cascade reaction using the benzyl alcohols and amines as the starting materials. The reaction proceeded via the sequential photo- catalytic oxidation of benzyl alcohols and imine condensation steps to generate the imine-linked COFs. Furthermore, the obtained TZ-BTCA-COF was employed as the photocatalyst to promote the photocatalytic oxidation of sulfides, affording sulfoxides in good yields. It is believed that this work not only enriches the photocatalytic synthetic methodology of COFs, but also expands the scope of monomers for COFs synthesis to benzyl alcohols, providing a new way for COFs synthesis.
