Multiple internal reflection FT-IR spectroscopy (MIRFTIRS) study of the electrochemical synthesis and redox process of poly (1,5-diaminonaphthalene)

The electrooxidation of 1,5-diaminonaphthalene (1,5-DAN) in acidic acqueous, methanol and organic media leads to polymer film on glassy carbon and Pt electrodes. The in situ infrared study during film growth and X-ray photoelectron spectroscopy (XPS) analysis indicate that the polymer structure consists of amine (-NH-C) and imine (-N=C) units, bearing free -NH2 groups in the chain. The polymer structure was confirmed by a multiple internal reflection FT-IR spectroscopy (MIRFTIRS) study of the film redox process and by the ability of poly(1,5-DAN) film to chelate copper ions.
