Abstract

Abstract: A supramolecular organic framework‐type photocatalyst, named TM‐SOF, is constructed by the self‐assembly of cucurbit[8]uril and a tetra‐arm monomer containing four N, N'‐dimethyl 2, 5‐bis(4‐pyridinium)thiazolo[5, 4‐d]thiazole (MPT) moieties. Benefiting from the multivalent assembly, a photocatalytically active supramolecular MPT dimer can be stably formed in TM‐SOF. In addition, TM‐SOF exhibits better stability against temperature, substrate, and light irradiation. As a result, TM‐SOF shows a significantly improved performance for the photocatalytic aerobic oxidation of aryl boronic acids and thioethers. It is anticipated that this line of research will provide a facile approach for fabricating high‐performance supramolecular photocatalysis systems. Abstract : A supramolecular organic framework ‐type photocatalyst is constructed by host‐guest complexation. Benefiting from the multivalent supramolecular assembly, it exhibits a higher effective concentration of catalytic sites and better stability to temperature, substrate, and light irradiation. As a result, the supramolecular organic framework shows improved catalytic performance in the photocatalytic oxidation of aryl boronic acids and thioethers.
