  • Hole transport polymeric compound and polymer light emitting diode using the same
    Patent number: 9373791
    Abstract: A hole transport polymeric compound and a polymer light emitting diode using the same. The hole transport polymeric compound includes a hole transport material, a thermal cross-linking agent containing an ethynyl group, and a compound represented by [Formula 1], and can be applied to a polymer light emitting diode. In addition, the hole transport polymeric compound has excellent hole transport capabilities and has stability in solvents so as to be insoluble in a solvent used upon stacking other organic layers and blocking electrons well.
    Type: Grant
    Filed: July 2, 2013
    Date of Patent: June 21, 2016
    Assignee: GWANGJU INSTITUTE OF SCIENCE AND TECHNOLOGY
    Inventors: Jae-Suk Lee, Beom-Goo Kang, Chang-Lyoul Lee, Kwanghee Lee, Hongkyu Kang
