  • Luminescent janus-type, two-coordinated metal complexes
    Patent number: 11920070
    Abstract: The co-linear or near co-linear structure of bimetallic Janus-type two-coordinated metal complexes may allow for a large transition dipole moment that can enhance the radiative lifetime. The symmetric nature of the bimetallic Janus complexes diminishes or eliminates the polar nature of the monometallic carbene-metal-amide/arene complexes.
    Type: Grant
    Filed: June 15, 2020
    Date of Patent: March 5, 2024
    Inventors: Peter I. Djurovich, Mark E. Thompson, Narcisse Ukwitegetse, Tian-Yi Li, Rasha Hamze
