BLUE-LIGHT-EMITTING IRIDIUM COMPLEX, IRIDIUM COMPLEX MONOMER, PHOSPHORUS POLYMER, AND ORGANIC ELECTROLUMINESCENCE DEVICE USING SAME

摘要

Provided are a blue-light-emitting iridium complex, an iridium complex monomer, a phosphorus polymer, and an organic electroluminescence device using same. The blue-light-emitting iridium complex contains a ligand having a low electron density structure, such as triazole or tetrazole. The iridium complex monomer containing a ligand having a polymerable vinyl group produces a blue phosphorous polymer through the polymerization with carbazole derivatives. The organic electroluminescence device comprises a first electrode, a second electrode, and a light-emitting layer stacked between the first electrode and the second electrode, wherein the light-emitting layer contains the above-described iridium complex or polymer containing the iridium complex.
