Abstract: Provided are a functionalized polycyclic aromatic hydrocarbon compound and a light-emitting device including the same. The functionalized polycyclic aromatic hydrocarbon compound is structurally stable, and exhibits high light-emission characteristics since aggregation caused by π-π stacking is inhibited, and thus may have high efficiency and long lifespan characteristics.
