摘要:
The disclosure relates to a novel polymer which is made up of repeating units of N,N,N'N'-tetrapheny-p-phenylenediamine. This polymer is thermoplastic and is soluble in industrially usable organic solvents. The polymer acquires high conductivity by doping with an electron acceptor. The polymer becomes insoluble in organic solvents when it is once doped with an electron acceptor and then dedoped, so that the polymer can be used as an active electrode material in electrolytic devices using an organic solvent. The polymer has electrochromic properties and undergoes two-stage oxidation and two-stage reduction to assume three differently stable states. The polymer exhibits pale yellow color in its reduced state, green color in the first-stage oxidized state and dark blue color in the second-stage oxidized state.

The invention relates to an electrochromic (EC) device having oppositely arranged two EC electrode layers. The first EC electrode layer uses Prussian blue, osmium purple or ruthenium purple and accordingly takes on a characteristic color by electrochemical oxidation, and the second EC electrode layer uses a transition metal oxide which takes on a characteristic color by electrochemical reduction, such as WO.sub.3. The space between the two EC electrode layers is filled with an electrolyte solution. When an EC device of this type is left in the bleached state for some period of time and then driven for coloration, the density of coloration is insufficient because of a decrease in the quantity of electricity in the oxidizing and coloring reaction of the first EC electrode layer. The invention solves this problem by using, as the electrolyte solution, a solution of a lithium salt and a sodium salt in an organic solvent prepared such that Na.sup.+ ion amounts to 3-30 mol % of the total of Li.sup.+ ion and Na.sup.+ ion.
