摘要
The electrochemical properties of MEH-PPV were: studied in ionic liquid([bmim](+)[PF6](-)) by cyclic voltammetry, chronoamperometry and AC impedance measurements. Both p- and n-doping of MEH-PPV were observed in the cyclic voltammograms, The chronoamperometric and AC impedance results indicate that the p-doping of MEH-PPV was controlled by the linear diffusion of counterions.
