The electrochemical behavior of the N,N'-diphenyl-1,4-phenylenediamine (B3) in acid solution has been investigated by in situ UV-vis and Raman spectroscopies. The electrogenerated species semiquinone form (B3(circle+)) and monoprotonated structure of B3 (B3(+)) have been characterized as the main products of B3 oxidation. The N,N'-diphenyl-1,4-benzoquinonediimine (B2Q1) species has also been characterized in B3 neutral solution and the B3(circle+) proton loss was attributed to proton absence in solution. Finally, a mechanism has been proposed concerning the electron and proton transfer that occurs during the oxidation process. (C) 2005 Elsevier B.V. All rights reserved.
