Abstract The present invention relates to an electron transport material and an organic electroluminescent device comprising the material in an electron transport layer. Tthe 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. La présente invention concerne un matériau de transport d'électrons et un dispositif organique électroluminescent comportant le matériau dans une couche de transport d'électrons. Les composés selon la présente invention en tant que matériau organique de transport d'électrons ont une propriété de transport d'électrons plus rapide par rapport à un matériau de transport d'électrons classique. Ainsi, un dispositif comprenant les composés selon la présente invention présentent une faible tension d'excitation, une efficacité élevée et d'excellentes propriétés de durée de vie. En outre, les composés de transport d'électrons présentent d'excellentes coordonnées de couleur, et, de ce fait, sont efficaces dans l'émission de la lumière bleue.
