摘要：

The vibrational spectroscopic properties of electrochemically synthesized poly(3,4-ethylenedioxythiophene) (PEDOT) films were studied with in situ Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) spectroscopy. PEDOT films were p-doped (oxidized) and n-doped (reduced) electrochemically. The doping induced infrared absorption spectra (IRAV spectra) during p- and n-doping of PEDOT films were studied comparatively. The results are discussed within the framework of a stronger localization of charges in the case of n-doping compared to p-doping. (C) 2000 Elsevier Science B.V. All rights reserved.
