Iridium Complex with Picolinic acid-N-oxide Ancillary Ligand and Organic Light-Emitting Diodes Containing Iridium Complex

摘要

The invention of the halogen compound is substituted aryl derivative with an alkyl or alkoxy substituent is introduced is a pyridine derivative and iridium complex introduced with picolinic acid as ancillary ligand is -N- oxide is introduced into the light-emitting layer and the iridium complex as a primary ligand It provides a phosphorescent organic electroluminescence device comprising a dopant. According to the invention the iridium complex synthesized due to the primary ligand and the subsidiary ligand introduced into an iridium light-emitting characteristics by not only it has been greatly improved, doping the iridium complex in the light emitting efficiency of light emission and the like to obtain a greatly improved element as compared with the conventional there was. ; Iridium complex (Iridium Complex), picolinic acid -N- oxide, an organic electroluminescent device (OLED)
