ABSTRACT:
Disclosed is an organic EL dye enabling to provide an organic EL device which is capable of emitting a light at a low voltage even when it has a single layer structure. Also disclosed is an organic EL device using such an organic EL dye. The organic EL dye is represented by the general formula (1): (Y—L)nXm wherein x is an n-valent charge-transporting group, Y is a light-emitting group, L is a linking group bonding the charge-transporting group and the light-emitting group, and m and n are respectively an integer not less than 1.
