Abstract:

In 1985 our laboratory initiated an investigation of the electrochemical reactions of molecular electron donoracceptor species dissolved in solid and semi-solid solvents. Poly-ether polymer electrolytes were selected as the model solid and semi-solid solvents, and the redox species have included ferrocenes, metal bipyridine complexes, tetracyanoquinodimethane TCNQ, and derivatives in which poly-ether chains have been attached to such species. The thrust of this investigation was firstly, to develop methodology for obtaining quantitatively interpretable electron transfer and mass transport rates of such molecular solutes in solid or semi-solid solvents, and secondly, to explore ways in which their solid state behavior differs form that familiar in fluid electrolyte solutions. This paper will draw together the essential aspects of the microelectrode-based solid state voltammetry methodology developed, and describe some of the special aspects of electron transfer and mass transport dynamics observed during this still ongoing investigation.
