  • Method for producing organic electroluminescent components
    Patent number: 6582888
    Abstract: A method for producing organic electroluminescent components having a structured electrode, in particular displays having a structured metal electrode, includes the following steps: At least two layers are applied onto a bottom electrode which is located on a substrate. The first layer is electrically insulating and is not damaged when the second layer is applied. A defined boundary remains between the two layers. The first layer has a higher solubility rate in a liquid developer than the second layer and it is possible to structure the second layer. The second layer is structured and the structure is transferred to the first layer. At least one organic functional layer is applied onto the second layer. A top electrode is deposited onto the organic functional layer.

  • 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 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.

  • Electroluminescent arrangement
    Patent number: 5518824
    Abstract: In an electroluminescent arrangement containing one or more organic layers, at least one of the layers is obtained by thermal or radiation-induced crosslinking and at least one charge-transporting compound is present per layer. The novel arrangements are very suitable, for example, for the production of displays.
