Ana-Maria Krestel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10707422
    Abstract: A method is provided for producing organic electrical layers having organic emitters that are phosphorescent at room temperature. Organic fluorescent emitters, together with organic complex ligands containing metal complexes, and at least one heavy main group metal, selected from the group comprising In, Tl, Sn, Pb, Sb and Bi, are deposited jointly inside a layer, and the heavy main group metal changes its coordination sphere by receiving the organic fluorescent emitter.
    Type: Grant

  • Patent number: 10519178
    Abstract: A bi-nuclear phosphorescent emitter according to the following formula is disclosed. The emitter may include metal atoms M1 and M2, fluorescent emitter ligands LF, LF?, terminal ligands LT, LT?, and bridging ligands LV, LV?, wherein M1 and M2 are In, Tl, Sn, Pb, Sb, and Bi; LF and LF? are comprise substituted or non-substituted C6-C70 aromatics or heteroaromatics; LV and LV? are fluorinated or non-fluorinated, bi-dentate C2-C30 heteroalkyl or heteroaromatics; LT and LT? are fluorinated or non-fluorinated, mono-, bi-, or tri-dentate C2-C30 O—, S—, N, heteroalkyl or heteroaromatics; and n and m are 1 or 2 independently of one another.

  • Patent number: 10347849
    Abstract: A method is provided for producing phosphorescent emitter layers composed of at least one organic fluorescent emitter F and at least one metal complex K including organic complex ligands L and at least one heavy main group metal M selected from the group consisting of In, Tl, Sn, Pb, Sn and Bi. The organic fluorescent emitter F and the metal complex K may be individually deposited as layers on a substrate and subsequently reacted with each other, wherein the coordination sphere of the heavy main group metal M is changed by receiving the organic fluorescent emitter F.

  • Patent number: 8921847
    Abstract: The invention relates to an OLEEC component and to a production process therefor. This component has an active layer including a novel emitter complex. This complex is formed by the coordination of low molecular weight semiconductors around a central cation. The complexation allows wet-chemical processing of low molecular weight semiconductors. This also allows formation of emitter complexes from effective hole or electron transport materials.
