Abstract
A method is described for the preparation of stable, adherent, thin layers of organic solvents interposed between the surfaces of graphite electrodes and aqueous supporting electrolytes in which they are immersed. The electrochemistry of reactants dissolved in the thin layers is examined and utilized to evaluate surface coverages and formal potentials for molecules, such as cobalt tetraphenylporphyrins, that do not exhibit useful electrochemical responses when adsorbed on graphite. The thin layers of organic solvent can be used to concentrate analytes by extracting them from dilute aqueous solutions to produce enhanced sensitivity in electroanalytical applications. Electron transfer across the liquid/liquid interface created by the presence of the thin layer of immiscible organic solvent is also demonstrated.
