  • Transition metal luminescent complexes and methods of use
    Patent number: 12116378
    Abstract: Described herein are transition metal complexes containing nickel(II), as the central metal atom, and tridentate and tetradentate ligands. The transition metal complexes also include an ancillary ligand with strong ?-donating properties. The ancillary ligand enhances the luminescence by increasing the chances of populating the emissive state. The transition metal complexes are emissive at room temperature and/or low temperature in various media, rendering them useful as light-emitting materials for OLEDs.
    Type: Grant
    Filed: December 9, 2019
    Date of Patent: October 15, 2024
    Assignee: THE UNIVERSITY OF HONG KONG
    Inventors: Vivian Wing-Wah Yam, Yip-Sang Wong, Man-Chung Tang, Mei-Yee Chan
