Provided are a blue-light-emitting iridium complex, an iridium complex monomer, a phosphorescent polymer, and an organic electroluminescent 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 polymerizable vinyl group produces a blue phosphorescent polymer through the polymerization with carbazole derivatives. The organic electroluminescent device comprises a first electrode, a second electrode, and a light-emitting layer interposed 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.
