Description
Summary:The photoelectrochemical oxidation of the compound tricarbonyl(N,N, N′,N′-tetramethyl-1,4- phenylenediamine)chromium 1, has been studied using a platinum channel electrode. Maximum photocurrents are seen at an irradiation wavelength of 365 nm corresponding to a metal-to-ligand charge transfer absorption. By means of in situ electrochemical EPR and quantitative photocurrent/mass ' transport measurements the process is shown to be of the photo-CE type and a rate constant and approximate quantum yield are reported.
