摘要
Poly(2-aminobenzothiazole)s were synthesized by electropolymerization method using 2-aminobenzothiazole (2ABT) and 6-ethoxy-2-aminobenzothiazole (EtO-2ABT) as the monomers. Cyclic voltammetry (CV) was used to determine the electrochemical oxidation-reduction characteristics. Electrochemical deposition of the polymers on indium tin oxide (ITO) coated glass surface was carried out by 鈥渂ulk electrolysis鈥?method. Spectroelectrochemistry was used to determine the spectral changes during the electropolymerization. All of the structural, optical and thermal characterizations were made using the polymers obtained on ITO by bulk electrolysis. The CV behaviours were investigated using glassy carbon (GCE) as the working electrode. Structural characterizations were made by FT-IR, NMR, and size exclusion chromatography (SEC) techniques. Optical properties were investigated by UV-vis and fluorescence analyses. Solid state electrical conductivities were measured on polymeric film surface by four point probe technique using an electrometer. Also, morphological characterizations were made by scanning electron microscopy (SEM) technique.
