Abstract

The present invention relates to an electron transport material and an organic electroluminescent device comprising the material in an electron transport layer. The compounds according to the present invention as an organic electron transport material have faster electron transport property compared to a conventional electron transport material. Thus, a device comprising the compounds according to the present invention shows low driving voltage, high efficiency, and excellent lifespan property. Furthermore, the electron transport compounds have excellent color coordinate, and thus are effective in blue light-emitting.
