Abstract : Ethylmercapto-substituted polythiophenes have been studied and when doped, they show considerably lower conductivity than the parent polythiophene. Calculations have shown that a significant fraction of the positive charge resides on the sulfur of the side chain and this is consistent with the low conductivity. Mechanistic electrochemical studies on these systems have been completed. Studies have continued on the fluorescence modulation induced by the redox switching of polypyrrole. A pyrrole substituted at the 3-position with anthracene has been prepared and characterized. A new soluble, electroactive polymer poly(bis-oxystyryldithiolene nickel) has been prepared and is being studied. A quartz crystal microbalance study of the electropolymerization of pyrrole has been completed and shows that is a useful quantitative tool for polymer deposition studies. A PMO study of aromatic conducting hydrocarbon oligomers and polymers has been completed.
