Abstract

Disclosed is an organic light emitting compound represented by Formula I:HAr-(L)-HAr  (I).Also disclosed is an organic light emitting diode including the organic light emitting compound. Particularly, the organic light emitting diode employs the organic light emitting compound as a material for electron injection and transport. The organic light emitting diode can be driven at a low voltage and has improved life characteristics compared to conventional organic light emitting diodes. Due to these advantages, the organic light emitting diode is useful in a variety of industrial applications, including displays and lighting systems.
