This project explores the electrochemical reactivity of electron transfer donor/acceptors dissolved in and diffusing through solid and semi-solid, ionically conductive media. The emphasis is on developing voltammetric experiments that are quantitatively interpretable in terms of the mass transport and electron transfer rates and thermodynamic equilibria of the redox solutes, and to exploit such experiments to probe their chemical and electrochemical behavior in the solid media. Techniques for quantitative voltammetry in solids were essentially unknown prior to initiation of this DOE project. We mainly employ poly(ethers)s containing dissolved metal salts electrolytes (``polymer electrolytes``), as prototype solid and semi-solid solvents. During this award year we have (a) concluded a study of plasticization chemistry in poly (ether) polymer electrolytes, (b) made progress in devising techniques for measuring the rates of electron transfer reactions in solid and semi-solid poly (ether)s, (c) continued efforts to design and understand the behavior of microband electrodes of various widths (0.1 to 10 {mu}m) in voltammetry of redox solutes, and (d) initiated synthetic efforts to attach ethylene oxide chains of various lengths to redox solutes.
