Abstract
Developing effective photocatalysts for the oxidation reaction is of great significance in chemical synthesis but is still challenging. Herein, linking photochromic triphenylamine with pyrene units by the in situ formed robust imidazole moieties, a covalent organic framework (COF), PyNTB-COF, containing a rare donor–acceptor-π-acceptor–donor (D-A-π-A-D) fragment, was successfully synthesized for photocatalytic aerobic oxidation. Structure characterizations confirm its crystalline framework, high porosity, and good stability. Property studies reveal its photoelectric semiconductor feature with high photoresponsive charge separation and migration activity derived from the D-A-π-A-D fragments, proven by the…
