Electrochromic Porperties of Fluorescent Dye Doped Poly(3,4-ethylenedioxythiophene) with Different Polymerization Times

Abstract:

The electrochromic properties of an electrochemical polymerized composite consisted of poly (3,4-ethylenedioxythiophene) doped with fluorescent yellow dye (PEDOT-FY) with different polymerization time are reported. The structures of PEDOT-FY were characterized via cycle voltammograms and spectroelectrochemistry. The PEDOT-FY films can appears orange-yellow and purple in the neutral state, and yellow-green and deep green in the oxidized state. Polymerizing for 6 min, the PEDOT-FY film comes out a new pair of oxidative and reductive peaks around 0.3V and-0.15V. In addition, the PEDOT-FY films also have short response times. It is shown that acid dye doping is an effective method to broaden the color change range of the electrochromic mateials.
