Studies on the Photoredox Behaviour of Copper(II) Acetato Complexes with Tripodal 4N Ligands in Methanol Solution.
Sprache des Titels:
The reactivity of copper(II) acetato complexes carrying the fully methylated tris(2-aminoethyl)amine ligand Me6tren under UV- and visible-light irradiation was studied in methanol solution. In the presence of water, the formation of colloidal copper nanoparticles occurred, indicating an irreversible decomposition of the copper(II) precursor under UV-light exposure. In dry methanol, a photoredox reaction involving the acetato ligand was observed, which leads to intermediate copper(I) complex formation. The potential of these processes for photocatalytic applications is briefly discussed and evaluated.
