Abstract
An Ir compound can be a blue phosphorescent material. An organic electroluminescent device can use such a material. An organic layer, such as a light emitting layer, can be composed of the Ir compound. An organic electroluminescent device including such an organic layer may exhibit high color purity and emits dark blue light. Such an organic electroluminescent device may have low consumption power.
