Abstract

Transparent and conductive films were grafted covalently on glass and ITO substrates with polysilsesquioxane having octithiophene, and their charge transport properties, were studied by electrochemical means. The cyclic voltammogram of oligothiophene fixed in silsesquioxane network was found to be broad because the conformations of oligothiophenes are restricted by the rigid polymer network. In situ electrical conductivities of the polymer films were measured simultaneously with doping levels at different potentials to yield charge carrier mobilities as a function of doping level of the polymer.
