The electrochemical behavior of poly(2-methoxy-5-dodecloxy-1,4-phenylene vi
nylene) (MD-PPV) is investigated by cyclic voltammetry and in situ spectroe
lectrochemical 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-dopin
g. That PEO affects the electrochemical behavior of MD-PPV/PEO blend positi
vely is also observed. (C) 1998 Elsevier Science Limited. All rights reserv
