چکیده انگلیسی
In this paper, a novel thiophene based monomer, 1-(pyren-1-yl)-2,5-di(thiophen-2-yl)-1H-pyrrole, PThP, was synthesized and characterized by 1H NMR and 13C NMR spectroscopic methods. The electrochemical behavior and electropolymerization of this novel monomer were performed on pencil graphite electrode (PGE) by cyclic voltammetry. The effect of solvent, dopant, scan number and scan rate on the electropolymerization and properties of the conjugated polymer films were investigated. The capacitive properties of the poly(PThP) films were tested by electrochemical impedance spectroscopy (EIS). The highest specific capacitance value was calculated for the conjugated polymer modified PGE that was obtained in 0.1Â M tetrabutylammonium perchlorate/dichloromethane solution for 30 cycles at 25Â mV/s scan rate as 25.45Â mFÂ cmâ2. The surface morphologies of the conjugated polymer modified electrodes were determined by scanning electron microscopy (SEM).
