Structure fine-tuning of benzoxazole-linked covalent organic frameworks (COFs) for photocatalytic hydroxylation of phenyl boronic acids

Novel structure fine-tuning benzoxazole-linked COFs H–BO-COF and MeO–BO-COF with different substitutes were successfully prepared. As photocatalysts for the hydroxylation of benzyl boronic acid, the performance of MeO–BO-COF is obviously better than that of H–BO-COF.
