ChemInform Abstract: Intramolecular Energy Transfer in a Chromophore-Quencher Complex.
Abstract
MLCT excitation of the complex (Ib) is followed by an intramolecular energy transfer to one of the chemically attached anthryl groups to give an anthryl triplet with a lifetime of 6 μs in MeCN at 295 K. Oxidative quenching occurs at this triplet and is followed by rapid intramolecular electron transfer to give the Ru(III) complex.
ChemInform Abstract
MLCT excitation of the complex (Ib) is followed by an intramolecular energy transfer to one of the chemically attached anthryl groups to give an anthryl triplet with a lifetime of 6 μs in MeCN at 295 K. Oxidative quenching occurs at this triplet and is followed by rapid intramolecular electron transfer to give the Ru(III) complex. The photophysical and photochemical properties of (Ib) are compared with those of the model complex (Ia).
