Iridium complex with picolinic acid as auxiliary ligand and application
-
Paragraph 0050-0052, (2021/07/17)
The invention belongs to the technical field of electroluminescent materials, and relates to a novel iridium complex. A main ligand of the iridium complex contains dibenzoheterocycle or aza-dibenzoheterocycle and an auxiliary ligand of the iridium complex is picolinic acid or a derivative thereof. The dibenzoheterocycle or aza-dibenzoheterocycle in the iridium complex molecule is helpful for regulating and controlling the luminescent color of the material, and is helpful for improving the stability of the material. The iridium complex disclosed by the invention is high in preparation yield, high in purity, easy to sublimate and purify and relatively high in luminous efficiency, and a device prepared by using the iridium complex as a luminous material is excellent in performance.
