Cathodic Electrochromism of Lutetium Diphthalocyanine Films.
Abstract
Cathodic electrochromism of lutetium diphthalocyanine films on insulating substrates was investigated by a moving-boundary technique. Reduction occurred by injection of electrons from a gold contact and cations from a liquid electrolyte. Light blue products formed with aqueous or organic solutions of alkali metal salts, while a dark violet product formed with aqueous hydrochloric acid. The dark material had a charge-carrier mobility of 8 times (ten to the minus 7th) cm squared/V-sec and an estimated bulk resistivity of 1,800 ohm-cm. Reduced forms of the dye appear to be solid cation conductors. (Author)
