Polythiazyl Films: Preparation and Use as Electrodes in Aqueous Solution

Electrodes constructed from single crystals of the polymeric conductor polythiazyl, (SN)~, have been studied in aqueous solution (1, 2). Depending on the choice of electrolyte, the background currents are smooth over a wide range, from greater than +0.9V to greater than--1.2V vs. SCE at the other extreme. The use of these electrodes is of considerable interest because of strong interaction of the mater ia l with cations (1) and in terms of producing (SN)x surface modified electrodes (2). Appl ications of such modi-fied electrodes for the photoinduced reduction of water (3) and the direct reduction of acetylene (4) have been reported. As the small surface areas possible for single crystal electrodes (1, 2) are a l imiting factor in their practical use at catalysts, appl ication of poly
