Polymer films on electrodes Part 29. Electropolymerized poly(7,14-diphenylacenaphtho[1,2-k]fluoranthene): electrochemistry and conductance of a novelelectrochromic hydrocarbon ladder polymer film

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.
