- Iridium complex with main ligand containing carbazolyl and application
-
The invention belongs to the technical field of electroluminescent materials, and relates to a novel iridium complex with a main ligand containing carbazolyl, in the structure, pyridine and derivatives thereof are introduced into the 1-site of carbazole to realize steric hindrance and limit the free relaxation of a benzene ring at the 9-site of carbazole, so that the non-radiative transition process of molecules can be inhibited. The iridium complex disclosed by the invention has very high photoluminescence quantum yield and short excited state service life. A device prepared from the iridiumcomplex is excellent in performance, has high external quantum efficiency, low starting voltage and low efficiency roll-off, and has potential application value in the field of OLED illumination and display.
