  • thiathlophene (EDiTT) was synthesized. The yield of the synthesis was about 29%. The monomer was identified by using NMR, IR and UV/Vis spectroscopic methods. Poly (3,4-ethylenedithiathiophene) (PEDiTT) was prepared using this monomer and FeCl$_3$. The deep blue green color of the product was changed into brown color by the reduction with $N_2$H$_4$. This was soluble to common organic solvents. Spectroelectrochemistry was used to characterize the PEDiTT. NMP was the best solvent for PEDiTT. PEDiTT/NMP solution was used for making SAM type thin film of the polymer on gold electrode. Electrochemical and IR spectroscopic methods were used to identify the thin film.

  • The nano or micro sized structures of conducting polymer had been prepared by synthesizing the desired polymer within the pores of template of nano or micro porous membrane filter. In this study, we had tried to fabricate conducting polymer microstructures on an electrode by using electrochemical deposition adopting template synthesis. Our attention was focused on two different things, attaching template on the electrode and fabricating microstructures only at limited areas of the electrode. A conducting polymer, PEDiTT (poly 3,4-ethylenedithi-athiophene) solution was blended with PVA(polyvinyl alcohol) solution and used as an conducting adhesive. After attaching template membrane, the electrode were immersed in 0.5M pyrrole in 0.1M KCI solution, and electrochemical polymerization was performed. The growth process of the microstructures studied by SEM. The electrochemical fabrication of conducting polymer was performed by using two-electrode system. A large working electrode and a micro scale disc electrode were used for the confined area synthesis. Polymerization potential was 4V in an electrolytic solution made of KCI in deionized water. The optimum polymerization conditions were, i.e. (4V/100sec) for $250{\mu}m$ electrode and (6V/30 sec) for $10{\mu}m$ electrode.
