A compound represented by Formula 1, and an organic light-emitting device including the compound:
In Formula 1, when L1 and/or L2 is a phenyl group, a pyridyl group, a pyrimidyl group, and/or a 1,3,5-triazinyl group having binding sites that are ortho- or meta- to each other, and the compound of Formula 1 is included the second hole transport layer (HTL2), the efficiency and luminance half-life of a device may increase due to the HTL2 having a higher T1 (e.g., triplet) energy level compared to examples in the related art using a para-substituted phenyl linker.
由式 1 表示的化合物,以及包括该化合物的有机发光器件:
在式 1 中,当 L1 和/或 L2 是苯基、吡啶基、嘧啶基和/或 1,3,5-三嗪基,这些基团具有彼此正交或偏交的结合位点,并且式 1 的化合物包含在第二空穴传输层(HTL2)中时,与相关技术中使用对位取代苯基连接剂的实例相比,由于 HTL2 具有更高的 T1(例如三重)能级,器件的效率和亮度半衰期可能会增加。
