Abstract: Studies have been conducted to determine characteristics of conducting polymers incorporating sulfated b-cyclodextrin (SbCD) used for electrochemically assisted preconcentration and speciation via solid phase micro-extraction. In order to deduce structural aspects of these systems, the effect of ratio of monomer to SbCD was explored through NMR studies of liquid phase (pre-electropolymerization) and solid phase (post-polymerization). By using SbCD as counter ions in polypyrrole and polythiophene, the reversibility of the redox reactions for L-dopa can be altered, whereas these polymers without added SbCD exhibit different performance as electrodes for dopa analysis. Information regarding the position and orientation of the SbCD ring within the polymer matrix can be related to surface morphology by comparison of SEM micrographs of poly(3-methylthiophene), polypyrrole, and poly(3,4-ethylenedioxythiophene) when SbCD is included in the polymerization mixture. The final aim is to use imprinting for chiral separation of a racemic mixture by inclusion of L-dopa in the electropolymerization solution.
