The dependence of electroconductivity on conjugation length as well as the related basic mechanism was investigated by chemical (FeCl3) oxidation of insulating polymers from N-vinylpyrrole (NVP) starting with different Fe/NVP ratios and different molecular weights. The results allow to establish that oxidation occurs mainly intrachain and that electroconductivity has a sharp increase for a conjugation length higher than approximately 15 NVP-units.

Abstract
The dependence of electroconductivity on conjugation length as well as the related basic mechanism was investigated by chemical (FeCl3) oxidation of insulating polymers from N-vinylpyrrole (NVP) starting with different Fe/NVP ratios and different molecular weights. The results allow to establish that oxidation occurs mainly intrachain and that electroconductivity has a sharp increase for a conjugation length higher than approximately 15 NVP-units.File in questo prodotto:
