Abstract

The PHOTO INDUCED ELECTRON TRANSFER reactions of three Ru(II) complexes with phenol ate ions of polyphenols (gallic acid, quercetin, p-coumaric acid, and ferulic acid) and thymol have been measured in 50 % aqueous acetonitrile at pH 11 and the observed QUENCHING constant (kq) values are sensitive to the nature of the ligand and the structure of the phenol ate ion. The change of kq values with DG0 is in accordance with the MARCUS SEMI CLASSICAL THEORY of electron transfer. The static as well as dynamic nature of QUENCHING is confirmed from the ground-state absorption studies. The reductive QUENCHING of the Ru (II) complexes by the phenol ate ions has been confirmed from the transient absorption spectra. The formation of phenoxyl radical as a transient is confirmed by its characteristic absorption at 400 nm.
