  • Polythiophene compositions for improving organic light-emitting diodes
    Publication number: 20050202274
    Abstract: The invention relates to compositions which include: (a) a polythiophene containing repeating units represented by the following general formula (I), wherein X represents, for example, —CH2—CH(CH2—O—(CH2)4SO3?H+)—; and (b) further polymers, that are different than polythiophene (a), and which contain SO3? M+ or COO?M+ groups. Also disclosed are electroluminescing (EL) arrangements that contain hole-injecting layers which include such compositions.
    Type: Application
    Filed: February 9, 2005
    Publication date: September 15, 2005
    Applicant: H.C. Starck GmbH
    Inventors: Andreas Elschner, Knud Reuter, Peter Lovenich
  • Polythiophene compositions for improving organic light-emitting diodes
    Publication number: 20050175861
    Abstract: Disclosed are compositions/formulations that include: polythiophenes (A) containing recurring units represented by the following general formula (I), in which is, for example, —CH2—CH2—; and two additional polymers (B) and (C), each having SO3?M+ or COO?M+ functional groups. Also disclosed are electroluminescent arrangements having hole-injecting layers containing the disclosed compositions.
