Abstract: The present disclosure provides a condensed-cyclic compound represented by Formula 1, in which one selected from R1 to R8 is a monoamine represented by Formula 2: The condensed-cyclic compound represented by Formula 1 may act as a hole transport material having a suitable energy level and band-gap. Further, the condensed-cyclic compound represented by Formula 1 has a fused core, and accordingly may have a high glass transition temperature (Tg), high melting point, and improved resistance to high temperatures. Therefore an organic light-emitting device including the condensed-cyclic compound represented by Formula 1 may retain high durability during storing and/or driving.

Abstract translation: 由式1表示的缩合环状化合物可以用作具有合适的能级和带隙的空穴传输材料。 此外，由式1表示的缩合环状化合物具有熔融芯，因此可以具有高玻璃化转变温度（Tg），高熔点和改善的耐高温性。 因此，包含由式1表示的缩合环状化合物的有机发光装置可以在储存和/或驱动期间保持高耐久性。
