Electrochemical behavior of poly(2-methoxy-5-dodecyloxy-1,4-phenylene vinylene) film electrode

Abstract

The electrochemical behavior of poly(2-methoxy-5-dodecyloxy-1,4-phenylene vinylene) (MD-PPV) is investigated by cyclic voltammetry and in situ spectroelectrochemical measurement. The energy gap of MD-PPV is determined to be 2.05 eV based on the onset potentials of electrochemical p-doping and n-doping. That PEO affects the electrochemical behavior of MD-PPV/PEO blend positively is also observed.
