Abstract:
Discussed is an organic compound of Formula 1 and an organic light emitting diode and an OLED device including the organic compound. In the organic compound, Ar1 is a heteroaryl group comprising a nitrogen atom, and Ar2 is a C6 to C30 aryl group, and R is a C1 to C10 alkyl group. The organic compound may be included in an emitting material layer of the organic light emitting diode as a host such that an emitting efficiency and a lifespan of the organic light emitting diode and the OLED device are improved.
