A new organic compound containing a naphthalene group as a core and a substitution group having electron transport ability is provided to produce an organic light emitting device with improved luminous efficiency, stability and lifetime. A new organic compound represented by the formula(3) is used to produce an organic light emitting device, wherein X^1 is N-R^7, S or O; X^2 is N-R^8, S or O; R^1 to R^8 are each independently H, C1-C30 alkyl group, C2-C30 alkenyl group, C3-C30 cycloalkyl group, C2-C30 heterocycloalkyl group, C5-C30 arylalkyl group, C5-C30 aryloxy group, C5-C30 aryl group or C5-C30 heteroaryl group. An organic light emitting device contains a cathode, an organic layer containing the organic compound represented by the formula(3) and an anode.
