In this work PPV films were prepared by electrochemical reduction of alpha,
alpha,alpha,alpha -tetrabromo-p-xylene in dimethylformamide and tetraethyla
mmonium tetrafluoroborate. To get more information about the mechanism behi
nd electrochemical polymerization of PPV and its doping reaction, in situ E
SR- UV-VIS measurements were made on the electrochemically synthesized cond
ucting polymer PPV.
