Devices based on poly- (3,4-dioxythiophene) derivatives that are electrochromically switched by protons

摘要

The invention relates to electrochromic arrangements in a layered structure which are characterized in that one layer contains an electrically conductive electrochromic polydioxythiophene, another layer comprises an electrolyte containing a protonic acid, and another layer comprises an ion storage or a mixture of ion storages.
