Abstract: Provided is a novel compound of Chemical Formula 1:




wherein Ar1 and Ar2 are each independently a substituted or unsubstituted C6-15 aryl, R1 and R2 are each independently hydrogen or deuterium, n1 is an integer of 1 to 7, and n2 is an integer of 1 to 6. Also provided is an organic light-emitting device including the compound. When a compound of Chemical Formula 1 is used as a material for hole injection, hole transport, light emission, or electron transport and injection of an organic electroluminescent device, a device having low voltage, high efficiency, and long lifetime characteristics can be obtained.
