  • Electrochromic system
    Patent number: 6241916
    Abstract: The novel electrochromic system comprises at least one reducible and at least one oxidizable substance OX2 and RED1 respectively, which are linked with one another via a bridge member, and is outstandingly suitable for use in an electrochromic device.

  • Electrochromic indicating device
    Patent number: 6207292
    Abstract: Electrochromic display devices, whose plates having conductive coatings are subdivided into segments which are electrically separated from one another, can be contacted individually and, between the plates, contain a solvent, specific electrochromic substances and optionally conductive salts, are distinguished by excellent edge definition and high contrast.

  • Electrochromic system
    Patent number: 6183878
    Abstract: The invention concerns an electrochrome system comprising a mixture of reducible and oxidizable substances RED1 and OX2, at lest one RED1′-OX2′ pair being covalently interlinked via a bridge and, for at least one RED1″ or OX2″ substance, the reciprocal conversion of the oxidized form and the reduced form being brought about by the fracture or formation of a &sgr;-bond. The electrochrome system is characterized by simplified electron transfer and reduced secondary reactions.
