Characterization and Conduction Behaviour in Charge Transfer Materials Based on Ethyl Silicate and Ethyl Dihydrogenborate

Abstract

Electrical conductivity of charge transfer materials based on ethyl
silicate dimethylsulphoxide with ethyl dihydrogenborate dimethyl-
sulphoxide at various temperatures has been reported. The current
voltage curves as a function of time have been obtained to determine
the role of ionic conduction in electronic conductors based on charge
transfer materials. The apparent activation energies, E_a of the compounds
were evaluated. The bulk electrical conductivity of the compound
at 1 : 1 molar ratio is found to be in the range of 10^-4 S cm^-1
at room temperature. Incorporation of hexakis dimethylsulphoxideiron
(IIl) perchlorate into the charge transfer material increases conductivity
up to 10^-3 S cm^-1 range.
