title: Observation of ion-transfer of photochemical reaction products of p-aminodiphenylamine across an aqueous | 1,2-dichloroethane solution interface by photo-modulation voltammetry with an ultraviolet laser.
abstract: Photo-modulation voltammetry with a 325-nm beam from a He-Cd laser was applied to an examination of a photochemical reaction of p-aminodiphenylamine. The photo-modulation voltammogram exhibited a peaked wave proportional to the concentration of p-aminodiphenylamine, and essentially agreed with a difference between linear scan voltammograms under irradiation and non-irradiation. From the absorption spectra of p-aminodiphenylamine and a pH dependence of the voltammograms, it was inferred that a dimer dication of p-aminodiphenylamine was photochemically formed and transferred from the aqueous solution to the 1,2-dichloroethane solution.
