Abstract
The present disclosure relates to an organic compound having improved luminescent properties, an organic light emitting diode and organic light emitting device including the organic compound, the organic compound having the following structure. The organic compound is a bipolar compound having both a p-type moiety and an n-type moiety and has high energy level, large energy bandgap and improved thermal stability. Applying the organic compound into an emissive layer of the OLED allows holes and electrons to be recombined at whole area of an emitting material layer, and thereby enhancing the luminous efficiency and the luminous lifetime of the OLED.
