Abstract
The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. Applying the organic compound into an emissive layer makes the OLED and the organic light emitting device lower their driving voltage, improves their luminous efficiency and color purity.
Claims22
An organic compound having the following structure of Chemical Formula 1:
