| Abstract | dc.description.abstract | In contrast to the UV-photoinduced ligand photoionization of the flavonoid complexes of FeIII,
redox reactions initiated in ligand-to-metal charge-transfer excited states were observed on irradiation of
the quercetin (1) and rutin (2) complexes of CuII. Solutions of complexes with stoichiometries [CuIIL2]
(L¼quercetin, rutin) and [CuII
2Ln] (n¼1, L¼quercetin; n¼3, L¼rutin) were flash-irradiated at
351 nm. Transient spectra observed in these experiments showed the formation of radical ligands
corresponding to the one-electron oxidation of L and the reduction of CuII to CuI. The radical ligands
remained coordinated to the CuI centers, and the substitution reactions replacing them by solvent
occurred with lifetimes t<350 ns. These are lifetimes shorter than the known lifetimes (t>1 ms) of the
quercetin and rutin radical s decay. | es_CL |
