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.
本发明公开了一种有机EL染料,能够提供一种能够在低电压下发光的有机EL器件,即使该器件具有单层结构。还公开了使用这种有机EL染料的有机EL器件。该有机EL染料由通式(1)表示:(Y-L)nXm,其中X是n价输运基团,Y是发光基团,L是连接基团,连接输运基团和发光基团,m和n分别是不小于1的整数。
