| 英文摘要 | Tetradentate open-chain Schiff base N□O□-ligands of acacen, benacen or salen type and fluoride anions F- coordinate to the iron(III) central atom in methanol forming the complexes [Fe(N□O□)(CH□OH)F]. The complexes do not undergo spontaneous redox changes when kept in the dark. Their irradiation into intraligand or ligand-to-metal charge transfer bands causes the photoreduction of Fe(III) to Fe(II) associated with oxidation of metanol to its radical CH□OH. The final products of the primary photoredox and secondary dark redox processes, Fe(II) and CH□O, are formed in a 2:1 molar ratio. The efficiency of the axial methanol ligand photooxidation is strongly wavelength dependent and influenced by the peripheral groups R of the tetradentate ligands. |
