  • Condensed-cyclic compound and organic light emitting device comprising the same
    Patent number: 10361373
    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.
