Abstract:

The copolymerization of 1,4-diethoxybenzene （DEB） and 3,4-ethylenedioxythiophene （EDOT） is achieved electrochemically in acetonitrile containing 0.1 mol·L^-1 tetrabutylammonium perchlorate （TBAP） as supporting electrolyte by direct anodic oxidation of the monomer mixtures on platinum and indium tin oxide （ITO） glass electrodesThe electrochemical properties of copolymer indicate that the electrochemical activity and capacitive property of the copolymers are much higher than that of pure poly （1,4-diethoxybenzene）（PDEB） due to the incorporation of EDOT unit into the copolymersThe structure and morphology of the copolymer are investigated by Fourier transform infrared （FT-IR） spectroscopy，scanning electron microscopy （SEM），respectivelyThe photoluminescence spectrum of copolymer and PDEB show that the emitting wavelength will red shift from 399nm to 530nm by introduction of EDOTThese results indicate that the electrocopolymerization of DEB and narrow band gap moiety provides a simple way to turn the emission color of PDEB
