Abstract

Thin films of a tetracyanoquinodimethane (TCNQ) oligomer adsorbed on optically transparent platinum electrodes have been studied using spectroelectrochemical techniques. In contact with aqueous electrolytes the electron acceptor sites in these modified electrodes are reduced to mixtures of the radical anion, TCNQxxx the dimer radical anion, TCNQxxx2, the dimer dianion TCNQ2-2, and the dianion, TCNQ2-. Electrolyte effects on the reduction process and the stability of the reduced films were studied. Both monovalent and divalent ions exhibited Nernstian potential dependence, and in the presence of Ca2+ ions the dianion state was stabilized. Counterion effects are suggested as the origin of variations in the wave shape in multicycle voltammograms.
