Blue-luminous iridium complex, iridium complex monomer, phosphorescent polymer and organic electroluminescent device having the same

摘要

blue light-emitting iridium complex , an iridium complex monomers , polymers , and provides a phosphorescent organic electroluminescence device using the same. Blue light-emitting iridium complexes containing ligands of low electron density and structure , such as a triazole or tetrazole, iridium complex containing a polymerizable monomer having a vinyl ligand forms a blue phosphorescent polymer by the polymerization reaction of the carbazole derivative The . The organic electroluminescent device is provided with a light emitting layer laminated between the first electrode and the second electrode and the first electrode and the second electrode , the light emitting layer comprises the above-mentioned iridium complex containing iridium complex or a polymer .
