Trenker, Stefan; Grunenberg, Lars; Banerjee, Tanmay; Savasci, Goekcen; Poller, Laura M.; Muggli, Katharina I. M.; Haase, Frederik; Ochsenfeld, Christian; Lotsch, Bettina V. published the artcile< A flavin-inspired covalent organic framework for photocatalytic alcohol oxidation>, Formula: C4H4N2O5, the main research area is diethyl bis formylphenyl alloxazine covalent organic framework preparation; aryl aldehyde preparation; alc oxidation catalyst FEAx COF.
Herein, the construction and use of a novel COF (FEAx-COF) photocatalyst, inspired by natural flavin cofactors was reported. The functionality of the alloxazine chromophore incorporated into the COF backbone was retained and study the effects of this heterogenization approach by comparison with similar mol. photocatalysts. The integration of alloxazine chromophores into the framework significantly extended the absorption spectrum into the visible range, allowing for photocatalytic oxidation of benzylic alcs. to aldehydes RC(O)H [R = 4-MeC6H4, 4-MeOC6H4, 4-t-BuC6H4, 2-thienyl] even with low-energy visible light. In addition, the activity of the heterogeneous COF photocatalyst was less dependent on the chosen solvent, making it more versatile compared to mol. alloxazines. Finally, the use of oxygen as the terminal oxidant renders FEAx-COF a promising and green heterogeneous photocatalyst.
