  • 4H-imidazo[1,2-a]imidazoles for electronic applications
    Patent number: 9502664
    Abstract: The present invention relates to compounds of formula (I), a process for their production and their use in electronic devices, especially electroluminescent devices. When used as electron transport and/or host material for phosphorescent emitters in electroluminescent devices, the compounds of formula I may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
    Type: Grant
    Filed: November 7, 2012
    Date of Patent: November 22, 2016
    Assignee: UDC Ireland Limited
    Inventors: Thomas Schaefer, Ute Heinemeyer, Nicolle Langer, Annemarie Wolleb, Christian Lennartz, Soichi Watanabe, Teresa Marina Figueira Duarte, Gerhard Wagenblast, Didier Bauer, Ingo Muenster, Christian Schildknecht, Heinz Wolleb
  • Metal complexes comprising diazabenzimidazolocarbene ligands and the use thereof in OLEDs
    Patent number: 9487548
    Abstract: The present invention relates to metal-carbene complexes comprising a central atom selected from iridium and platinum, and diazabenzimidazolocarbene ligands, to organic light diodes which comprise such complexes, to light-emitting layers comprising at least one such metal-carbene complex, to a device selected from the group comprising illuminating elements, stationary visual display units and mobile visual display units comprising such an OLED and to the use of such a metal-carbene complex in OLEDs, for example as emitter, matrix material, charge transport material and/or charge or exciton blocker.
