  • Stable and efficient electroluminescent materials
    Patent number: 8603645
    Abstract: An organic light emitting device is provided. The device has an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer may include a molecule of Formula I wherein an alkyl substituent at position R?5 results in high efficiency and operational stability in the organic light emitting device. Additionally or alternatively, the emissive layer may include a metal-ligand complex in which the ligand is an aryl or alkyl substituted phenylpyridine ligand.
    Type: Grant
    Filed: November 16, 2010
    Date of Patent: December 10, 2013
    Assignee: Universal Display Corporation
    Inventors: Raymond Kwong, David Knowles, Bin Ma, William Ceyrolles
