Abstract: A dibenzoborole-based compound and an organic light-emitting device including the same. The dibenzoborole-based compound is represented by the formula A1-(A2)n1, wherein A1 may be selected from specific aromatic and non-aromatic carbocycles and heterocycles, n1 may be an integer selected from 1 to 10, and each A2 moiety may independently be selected from a group represented by Formula 2: The dibenzoborole-based compound may be included in the hole transport region or hole transport layer. When the dibenzoborole-based compound has strong electron acceptor characteristics, the hole injection barrier between the anode and the organic layer may be reduced, and thus, an organic light-emitting device including the dibenzoborole-based compound may have high efficiency and a long lifespan.
