A compound having a high glass transition temperature, high electric stability, and/or high luminescent efficiency, and an organic light-emitting device including an emitting layer including the compound, which is represented by Formula 1:
In Formula 1, A may be a moiety formed by fusing a substituted or unsubstituted indole group, as represented by Formula 1-1:
When the compound represented by Formula 1 is used as a material for an emitting layer, an organic light emitting device including the compound may exhibit decreased driving voltage and improved efficiency and lifespan, as compared to OLEDs containing compounds that are available in the related art.
具有高玻璃转变温度、高电稳定性和/或高发光效率的化合物,以及包括该化合物的发射层的有机发光器件,该化合物由下式1表示:在式1中,A可以是由融合取代或未取代的吲哚基组成的基团,如下式1-1所示:当使用由式1表示的化合物作为发射层的材料时,包括该化合物的有机发光器件可能表现出较低的驱动电压和改善的效率和寿命,与包含相关技术中可用化合物的OLED相比。
