Phenyl Extended Naphthalene?Based Covalent Triazine Frameworks as Versatile Metal?Free Heterogeneous Photocatalysts

Two new covalent triazines frameworks (CTFs) containing phenyl extended naphthalene units (with and without methoxy groups in the core) are prepared by thermal microwave activation. Both procedures yield similar chemical structures combining triazine acceptor with donor aromatic groups, but they generate some differences morphology, structural organization, CO2 adsorption capacity, optical properties. Besides, of core have also influence these The resulting CTFs efficiently utilized as metal-free heterogeneous photocatalyst for selective aerobic oxidation sulfides dehydrogenative cross-coupling reactions under visible-light irradiation, showing a high stability.
