Abstract: Provided are novel compounds of Chemical Formula 1:





where Y is S or O, A is naphthalene ring, L1 and L2 are each independently, a direct bond or a substituted or unsubstituted C6-60 arylene, Ar1, Ar2, Ar3 and Ar4 are each independently a substituted or unsubstituted C6-60 and or a substituted or unsubstituted C2-60 heteroaryl containing at least one of N, O, and S, R1 is each independently, hydrogen, deuterium, a substituted or unsubstituted C1-60 alkyl or a substituted or unsubstituted C6-60 aryl, and m is an integer of 0 to 6. The compounds exhibit high stability to electrons and holes. Also provided is, an organic light emitting device including the compounds, and the devices exhibit greatly improved lifetime characteristics while maintaining high efficiency because of the stability of the compounds of Chemical Formula 1.
