Description
Summary:The electrooxidation of 2-methyl-5-amino-1,4-naphthoquinone (MANQ) on platinum or glassy carbon (GC) electrodes in acetonitrile leads to poly(2-methyl-5-amino-1,4-naphthoquinone) (PMANQ) films. Films were characterized by UV–VIS, X-ray photoelectron spectroscopy (XPS), ex situ FT-IR and in situ multiple internal reflection FT-IR spectroscopies (MIRFT-IRS). Results converge to a definition of the polymer structure, which is of the polyaniline type, bearing one methylquinone group per monomer unit. The electrochemical properties of PMANQ film in organic and aqueous media were studied by MIRFT-IRS and in situ d.c. conductivity. The film is conducting in negative as well as in positive potential range.
