N -Ethyl substituted poly(3,4-ethylenedioxypyrrole), a new electrochromic polymer, has been produced and its spectroelectrochemical properties have been investigated. This material displays multicolor electrochromism, switching between green, violet, and grey. Three different electrochromic devices have been laminated and evaluated using the electrochromic polymer, an ion-conducting polymer electrolyte, and one of the following counterelectrodes: tungsten oxide, polyaniline, or poly-di-methyl-(3,4-propylenedioxythiophene). |
