Abstract

The electrochemistry of tetracyanoquinodimethane (TCNQ) modified electrodes in contact with simple alcoholic solvents containing lithium salt electrolytes has been studied. Cyclic volammetric responses characteristic of each alcohol are obtained for 0. 1M LiCl/ROH solutions where R equals CH//3,CH//3CH//2,CH//3CH//2CH//2, and CH//3CH//2CH//2CH//2. Film stability in the minus 2 oxidation state and persistence on the electrode were greatly improved in the alcohol solvents relative to the behavior in water. Based on the voltammetric responses, reversible and facile swelling of the polymeric TCNQ films was found when the electrodes were transferred between solvents and electrochemically cycled between the neutral and reduced forms.
