  • Hybrid host materials for electrophosphorescent devices
    Patent number: 9040718
    Abstract: Compounds (including polymers) for use in hybrid host materials which can be used in electroluminescent devices. The compounds comprise at least one electron-transporting moiety and at least one hole-transporting moiety which are joined by a flexible linker. Hybrid host materials comprising the compounds exhibit stability against phase separation, elevated glass transition temperature, morphological stability against crystallization, and isolation of the electron transporting moiety and hole transporting moiety ?-systems.
    Type: Grant
    Filed: January 22, 2010
    Date of Patent: May 26, 2015
    Assignee: The University of Rochester
    Inventors: Shaw H. Chen, Lichang Zeng, Thomas Yung-Hsin Lee
