Title:
d10 METAL CARBENE COMPLEXES FOR OLED APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2023/093754
Kind Code:
A1
Abstract:
Described herein are two-coordinated d10 metal carbene complexes containing (i) Cu (I), Ag (I), or Au (I), (ii) a pyrazine-fused NHC ligand or a pyridine-fused NHC ligand, and (iii) a carbazole ligand, a pyrido [2, 3-b] indole ligand, or a pyrido [3, 4-b] indole ligand. The radiative properties of the compounds can be controlled by thermally activated delayed fluorescence. The emission colors of the complexes can be tuned by using carbazoles with varying donor strength. Also described are methods of using the complexes.
