- Abstract
- The electrochemical polymerization of 3,4-ethylenedioxythiophene in the presence of a water-soluble Na+-containing fullerene with hydroxyl groups was studied. Spectral methods for monitoring the progress of electrosynthesis have shown that during the polymerization of 3,4-ethylenedioxythiophene, fullerenol is included in the film composition, regardless of the fullerenol concentrations used in the synthesis. The electronic structure, morphology, spectroelectrochemical, electrochemical properties and near-IR photoconductivity of composite films of poly-3,4-ethylenedioxythiophene with fullerenol were studied for the first time. A mechanism of photoconductivity has been proposed, related to the fact that during photoexcitation of the composite, electron transfer from the polaron (bipolaron) state of poly-3,4-ethylenedioxythiophene to the LUMO level of fullerenol increases the concentration of photogenerated charge carriers.
