Abstract: The present disclosure relates to an organic compound including at least one carbazolyl moiety fused with an alicyclic or hetero alicyclic ring and linked to directly or via a linker to a triazine moiety and at least one blocking moiety linked the triazine moiety, an organic light emitting diode and an organic light emitting device including the organic compound. The organic compound can implement high luminous efficiency as enhancing delayed fluorescent property, minimize reduction of the luminous lifespan caused by substituent degradation, and can secure high triplet energy level owing to no conjugation extensions. The organic light emitting diode and the organic light emitting device using the organic compound can have beneficial luminous efficiency and the luminous lifespan.
