The electropolymerization of 7,14-diphenylacenaphtho[1,2-k]fluoranthene on
a platinum or indium tin oxide (ITO) electrode produces an electroactive fi
lm which displays fluorescence and electrochromism. We report a study of th
e electrochemical properties and other characteristics of this film, such a
s the resistance dependence by the potential applied to the electrode. In p
articular, the film showed dramatic changes in the resistance and color as
a function of the potential applied to the film because of changes in the e
lectronic state of the polymer. Atomic force microscopy, scanning electroch
emical microscopy, and electrochemical quartz crystal microbalance studies
were also carried out to characterize the polymer film. (C) 2001 Elsevier S
