• The copolymerization of carbazole(C) and poly3-ethyl-3-({[6-(3-thienyl)hexyl]oxy}-methyl)oxetane(PTO) was successfully achieved electrochemically in CH2Cl2 containing 25% boron trifluoride diethyl etherate BFEE(by volume) as supporting electrolyte by direct anodic oxidation of the monomer mixtures on platinum or an optically transparent ITO electrode. As-formed copolymer own the advantages of PTO, such as good electrochemical behaviors, excellent ambient stability. The structure of the copolymer were investigated by UV-vis, fluorescence spectra and thermal analysis, respectively. The fluorescence spectra indicate that PPTOC films are yellow-light emitters. Thermal analysis studies confirmed PPTOC has a good thermal stability.
