Abstract: Poly(5-arnino-l-naphthol) is a new conducting polymer, obtained by electropolymerization of 5-amino-l-naphthol. Raman spectroscopy confirms the structure which consists of amine (-NH-C) and imine (-N = C) links between naphthalene rings, characteristic of a polyaniline-like structure. Its redox properties were investigated in aqueous acid (pH 0) by in situ Raman spectroscopy. Some amine units are reversibly transformed into imine groups on oxidation.CNRS assisted in meeting the publication costs of this articl… Show more

“…Thus, AN units bind with each other to produce an oligomer. Similar polymerization mechanisms for aminonaphthol homopolymers and some copolymers have been previously reported in the literature [31][32][33][34]. The molecular weight of OAN was determined by SEC.…”

“…In here, a radicalic cation mechanism is also suggested as given in Scheme 2 [31,32]. In the aqueous solution of HCl, naphthylamine groups convert to their radical cations by adding an oxidant.…”

“…The height of the RGO sheet calculated from AFM was of 60 nm. According to Figure 9, the main Raman lines of P5A1N electrosynthesized onto the Au electrode have peaks at 738-846-939, 1193, 1276, 1322-1338, 1428, 1579 and 1620 cm -1 , these being assigned to the vibrational modes of the C-H bond, the deformation of the C-C bond in naphthalene nuclei, stretching of the C-H bond, stretching of the C-C and C-O bonds, bending of the C-N bonds and the stretching of the C-C and C=C bonds in naphthalene nuclei [10,11]. The Raman spectrum of P5A1N electrosynthesized onto the Au electrode covered with the RGO sheets highlights as the main difference in comparison to the P5A1N electrogenerated onto the blank Au electrode, a change in the value between the intensities of the Raman lines peaking at 1579 and 1620 cm −1 from 1.46 (blue curve in Figure 9) to 1.87 (red curve in Figure 9).…”

“…Another application of P5A1N envisaged to be developed in this work is in the field of the composite materials based on reduced graphene oxide (RGO) sheets functionalized with macromolecular compounds. The main experimental techniques used until now for the characterization of P5A1N were infrared absorption spectroscopy [8], Raman scattering [9][10][11], UV-Vis spectroscopy [10], X-ray photoelectron spectroscopy [11] and atomic force microscopy [12]. As shown in several articles (e.g., [13,14]), IR absorption spectroscopy and Raman scattering were reported to be two tools useful in assessing of the functionalization processes of the RGO sheets with macromolecular compounds.…”

“…Oxidation-reduction could be followed by a doping-undoping process involving counterions. The doping process was previously described for conducting films [17][18][19] including heteropolyanions. 17,20,21 Our results showed that polyanions like oligonucleotides can act as the doping anions and be efficiently retained in the conducting film under low ionic strength conditions.…”
