Abstract
A novel phosphorescent material containing an iridium metal compound and an organic electroluminescent device using the same are provided. When used for an emissive layer of an organic electroluminescent device, the phosphorescent material offers greater luminescent efficiency and improved driving voltage characteristics, compared to conventional red luminescent materials, and reduces the amount of power consumed in the organic electroluminescent device.
