Article Citation - WoS: 6Citation - Scopus: 6Anodic Oxidation of N-Substituted Dipyrrolyl Linked by Polyether Bridge(Taylor & Francis inc, 2006) Cihaner, AtillaElectroactive polymer containing polyether pseudo-cages has been synthesized by anodic oxidation of 1,11-bis(1,1-pyrrole)-3,6,9-trioxaundecane (I) using acetonitrile (ACN) as solvent and tetrabutylammonium perchlorate (TBAClO 4 ) as supporting electrolyte. Electrochemical behavior of monomer I and its polymer, poly-I , were studied using cyclic voltammetry (CV) and UV-VIS spectroscopic techniques. Also, a doping/dedoping study was carried out using electron spin resonance (ESR) and UV-VIS spectroscopic techniques. Thermal behavior of the product was studied using differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA).Article Citation - WoS: 11Citation - Scopus: 14Electrochemical Synthesis of New Conducting Copolymers Containing Pseudo-Polyether Cages With Pyrrole(Elsevier Science Sa, 2007) Cihaner, AtillaConducting copolymers have been synthesized via electrochemical oxidation of pyrrole (Py) in the presence of monomer 1, 11 -bis(1,1-pyrrole)-3,6,9-trioxaundecane (I) in an electrolytic solution containing 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)) dissolved in acetonitrile. It is observed that reversible redox behavior of poly(I-co-Py)s shifts to more positive potentials with the increasing amount of I in the comonomer mixture, indicating formation of a copolymer. It is also found that increasing the ratio of I in the comonomer mixture decreases the conductivity of the obtained polymer films. The dark electrical conductivity measurements in the temperature range of 300-100 K revealed the extrinsic type of conduction with activation energy values being in the range of 82.3-16.9 meV.
