PURPOSE: An arylamine-based light-emitting compound is provided to improve thermal stability, light-emitting ability and electric property, thereby useful for the hole injection material, the hole transfer material and/or luminescent material of an organic electroluminescent device. CONSTITUTION: An organic luminescent compound is in the chemical formula 2a. In the chemical formula 2a, Ar1 and Ar2 are phenyl group, naphthyl group, biphenyl group or terphenyl group which is substituted or unsubstituted by alkyl group. L1 is phenylene group, naphthylene group, biphenylene group, terphenylene or pyrenylene which is substituted or unsubstituted by alkyl group. E1 is C10-60 aromatic substituent not including nitrogen. Two among Ar1, Ar2 and L1, can form fused ring by connecting each other. An organic electroluminescent device comprises anode, cathode, and organic layers inserted between the anode and the cathode. The organic layers comprise the organic luminescent compound. |
