Abstract
An organic compound, an organic light emitting diode including the compound, and an organic light emitting device including the organic light emitting diode are disclosed. The organic compound may include a fused hetero aromatic moiety having a p-type property and an aza-acridine moiety having an n-type property bonded to the fused hetero aromatic moiety via an aromatic or a hetero aromatic linker. The organic compound has relatively high energy level since it includes plural fused hetero aromatic rings. Holes and electrons can be recombined in an emitting material layer in a balanced manner since the organic compound has a bipolar property. The organic light emitting diode and the organic light emitting device including the organic compound have enhanced luminous efficiency and luminous lifetime.
