Abstract
A condensed cyclic compound represented by Formula 1 below and an organic light-emitting device (OLED) including the condensed cyclic compound are presented. Arand Arin Formula 1 are each independently one of a hydrogen atom, an aryl or heteroaryl group and an arylamino group, at least one of Arand Arbeing a substituted or unsubstituted 1,2,4-triazol-4-yl group; Land Lin Formula 1 are linking groups, each independently one of a cyclic or noncyclic, saturated or unsaturated hydrocarbon group and a heteroarylene group; a and b in Formula 1 are each independently one of 0 or 1; and Rto Rin Formula 1 being each independently one of a variety of inorganic and organic substituents including cyclic or noncyclic, saturated or unsaturated and aromatic, nonaromatic or heteraromatic groups. The OLED may have a low driving voltage, a high emission efficiency and long lifespan characteristics.
