Solvation/desolvation during the redox transformation of poly(3-methylthiophene)

Abstract

Solvation/desolvation effects were studied during the redox transformation of poly(3-methylthiophene) by electrochemical quartz crystal microbalance technique. The effect was demonstrated by studying the phenomenon in different solvents, and comparing the results after a solution change. From the data obtained with the same film transferred between nitrobenzene and acetonitrile in both directions, the solvation effect was directly evidenced, and the virtual molar mass of the moving species in and from the same film was determined to illustrate semi-quantitatively the effect of the solvation.
