The influence of Li ion pairing on the voltammetric redn. of anthraquinone in MeCN is reported. On Au electrodes, the single electron redn. generates a radical anion which forms a complex with Li cations from the electrolyte. In situ ESR studies support this finding, and signal intensity measurements are used to est. a value for the complexation equil. const. Values calcd. were of the of the order of 6000 mol-1 dm3. Potential shift measurements and Digisim modeling are in support of a complexation mechanism in which a little of the complex ppts. on the electrode surface. The effect of Li ion pairing is also demonstrated for the case in which 1-anthraquinonyl groups are covalently attached to multiwalled C nanotubes abrasively immobilized on a basal plane pyrolytic graphite electrode.
