Electrochromic assembly based on poly(3,4-ethylenedioxythiophene) derivatives and a UV-stabilized gel electrolyte
First Claim
1. A UV-stabilized electrochromic assembly having a UV-stabilized gel electrolyte comprising an immobilized UV absorber in a layer structure, wherein one layer is an electrically conductive electrochromic polydioxythiophene and a further ion-storage layer is one or more ion-storage compounds selected from the group consisting of compounds having the formulas
whereinMe1 and Me2 each represent a metal of transition group III, IV, or V of the Mendeleev Periodic Table,Me3 and Me4 each represent a metal of transition group VI or VIII of the Mendeleev Periodic Table,Me5 represents a metal of transition group V of the Mendeleev Periodic Table,x represents a number from 0.001 to 5,y represents a number from 0.001 to 5, andM represents a metal of main group I of the Mendeleev Periodic Table or a proton.

Abstract
UV-stabilized electrochromic assemblies having a layer structure, characterized in that one layer contains an electrically conductive, electrochromic polydioxythiophene and a further layer contains an inorganic ion-storage compound based on metal oxides or a mixture of such ion-storage compounds, where the gel electrolyte is chemically crosslinked and contains chemically bound UV absorbers which cannot migrate as UV protection.
