    Abstract: A material for an organic electroluminescent device, represented by Formula 1, and an organic electroluminescent device including the same. The material for an organic electroluminescent device according to an embodiment of the present disclosure may be a triamine derivative in which the nitrogen atoms are connected (e.g., coupled) via the meta ring positions of L1 and L2 linkers, which may be represented by Formula 2. When the material for an organic EL device according to an embodiment of the present disclosure is used in a hole transport layer adjacent to an emission layer, the charge transport properties may be improved, and the lifetime of the organic EL device may be increased.

    Abstract translation: 当根据本公开实施例的有机EL器件的材料用于与发射层相邻的空穴传输层时，可以提高电荷传输性能，并且可以增加有机EL器件的寿命。
