Electrochemistry in Liquid Crystals
Abstract
Over the last two years our studies have focused on further studies of electrochemical reactions in liquid crystals as well as the use of x rays as insitu probes of electrochemical interfaces. In the area of liquid crystals, we have studied the electrochemical response of electrodes modified with cholesteryl oleyl carbonate (COC; a cholestric phase with optical activity) and on the differences in the electrochemical responses of the optically resolved forms of Ru(bpy)3+2 at such electrode surfaces. We have investigated a wide range of preparations including the modification of electrode surfaces with polymer films containing COC as a dpoant and have found these to exhibit a high degree of enantioselective discrimination (ca.20%) in the oxidation of (+) and (-) (Ru(bpy)3)+2. We have also investigated the effect of adding chiral supporting electrolytes such as 2,3 dimethoxy bis 1,4 dimethlamino butane and again, significant chiral discrimination was observed.
