  • Electroluminescent polymers and the use thereof
    Patent number: 7947382
    Abstract: The present invention relates to polymers which contain novel structural units of the formula (I). The materials according to the invention exhibit improved efficiency and a longer lifetime on use in a polymeric organic light-emitting diode.
    Type: Grant
    Filed: April 26, 2005
    Date of Patent: May 24, 2011
    Assignee: Merck Patent GmbH
    Inventors: Arne Büsing, Susanne Heun, Silke Türk, Corinna Leske
  • Conjugated polymers containing arylamine units, the representation thereof and the use of the same
    Patent number: 7910687
    Abstract: The present invention relates to conjugated polymers which contain specific fused arylamine structural units. The inventive materials have improved efficiency at a high illumination density and are therefore suitable in particular for use in what are known as passive matrix displays.
    Type: Grant
    Filed: October 17, 2003
    Date of Patent: March 22, 2011
    Assignee: Merck Patent GmbH
    Inventors: Arne Büsing, Esther Breuning, Hubert Spreitzer, Heinrich Becker, Corinna Leske
  • Conjugated polymers containing dihydrophenanthrene units and use thereof
    Patent number: 7723455
    Abstract: The invention relates to conjugated polymers containing novel structural units according to formula (1). The inventive materials are characterized by increased efficiency and a longer service life when used in polymer organic light emitting diodes.
    Type: Grant
