Title: Spectral characterization of the one-electron oxidation product of cis-Bis(isothiocyanato)bis(4,4{prime}-dicarboxylato-2,2{prime}-bipyridyl) Ruthenium(II) complex using pulse radiolysis

Abstract

The spectral characterization of the oxidized form of ruthenium(II) cis-di(isothiocyanato)bis(4,4{prime}-dicarboxy-2,2{prime}-bipyridyl), (commonly known as N3-dye) in aqueous solution is made by reacting the title compound with pulse radiolytically generated radicals N{sub 3}{sup {sm_bullet}} and Br{sub 2}{sup {minus}{sm_bullet}}. The one-electron oxidized form of Ru(II)-dye initially formed in both these oxidation reactions shows absorption maxima at 320 and 740 nm. Following radiolysis, the one-electron oxidized form of Ru(II)-dye undergoes further transformations to yield a stable product that exhibits a characteristic absorption maximum at 440 nm. The preliminary results provide the spectral evidence for the formation of two different species that follow the oxidation of Ru(II)-dye.
