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