Naphthalene-based Donor-Acceptor Covalent Organic Frameworks As an Electron Distribution Regulator for Boosting Photocatalysis.

By incorporating the electron-rich naphthalene and electron-deficient triazine as an electron donor and an electron acceptor, a new donor-acceptor covalent organic framework as an electron distribution regulator was obtained for boosting photocatalytically oxidative coupling of benzylamines and selective oxidation of thioethers under the irradiation of green light (520 nm).
