Patents by Inventor Joern Pommerehne

Joern Pommerehne 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: 9353065
    Abstract: The present invention relates to compounds of the formula (I), a process for their preparation and their use in organic light emitting diodes (OLEDs), especially as host for phosphorescent compounds. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or special characteristics of electroluminescent devices.
    Type: Grant
    Filed: March 19, 2008
    Date of Patent: May 31, 2016
    Assignee: BASF SE
    Inventors: Thomas Schäfer, Peter Murer, Frédérique Wendeborn, Beat Schmidhalter, Kristina Bardon, Andrea Ricci, Joern Pommerehne
  • Patent number: 8299706
    Abstract: A process for producing increased service life of organic, electro-optical elements is provided. The process includes the steps of: providing a substrate, applying a first conductive layer, applying at least one layer that includes at least one organic, electro-optical material, applying a second conductive layer, and depositing at least one layer with a vitreous structure.
    Type: Grant
    Filed: July 30, 2007
    Date of Patent: October 30, 2012
    Assignee: Schott AG
    Inventors: Clemens Otterman, Oliver Fritz, Dietrich Mund, Joern Pommerehne

  • Publication number: 20090011217
    Abstract: The invention relates to a method for applying a porous glass layer. It is proposed to apply a porous glass layer by means of a PVD method. Porosity factor and average pore size can be varied by means of the process parameters such as pressure and deposition rate, as well as by deliberate addition of extrinsic substances.
