PURPOSE: A novel organic electroluminescent compound is provided to prepare an OLED device with good driving durability of a device due to excellent lifetime property of materials. CONSTITUTION: A novel organic electroluminescent compound is represented by chemical formula 1 or chemical formula 2. In formulae, R1 and R2 are independently (C5-C60) aryl or (C5-C60) heteroaryl; and Ar1-Ar4 are independently hydrogen, halogen, (C1-C60) alkyl, (C6-C60) aryl, (C4-C60) heteroaryl, 5-6 ring heterocycloalkyl containing at least one from N, O, and S, (C3-C60) cycloalkyl, tri (C1-C60) alkylsilyl, (C1-C60) alkyl (C6-C60) arylsilyl, tri (C6-C60) arylsilyl, adamantyl, (C7-C60) bicycloalkyl, (C1-C60) alkoxy, cyano, (C1-C60) alkyl amino, (C6-C60) arylamino.
