Tiivistelmä
Electropolymerization of 2-methoxynaphthalene in TBAPF(6)-ACN and characterization of the formed film were studied by cyclic voltammetry (CV), electrochemical quartz crystal microbalance (EQCM), Fourier transform infrared spectroscopy (FT-IR) and by scanning electron microscopy (SEM). Oxidation of 2-methoxynaphthalene at a Pt electrode was performed by CV in a three-electrode electrochemical cell. EQCM was used during polymerization as an in situ technique, detecting the continuous mass increase with the number of potential cycles. The redox behavior (both p- and n-doping) of the film was studied by CV in monomer-free, TBAPF6-ACN, electrolyte solution. The electrochemical response from the anodic charging (p-doping) of the film was found to consist of a strongly increasing current but with no well-defined oxidation peak. Upon discharging a distinct reduction peak was observed. The cathodic charging and discharging (n-doping) responses consisted of well-resolved redox peaks. Both the anodic and the cathodic reactions are reversible and the film did not show any evidence of degradation when cycled between -2.4 and +1.3 V. Transmission FT-IR spectra of the freshly prepared neutral film of 2-methoxynaphthalene and of the neutral polymer after n-doping were recorded. These results gave evidence of oligomer and macromolecular formation due to the fact that new bands in the region of 600-900 cm(-1) were observed. The morphology of the electrosynthesized film was studied by SEM. (C) 2003 Elsevier Science B.V. All rights reserved.
