NOVELTY - An organic electroluminescent anthracene compound (I) or (II) is new.    USE - In organic electroluminescent device (particularly organic electroluminescent display), and organic solar cell (claimed). Also useful to manufacture organic light emitting diodes.    ADVANTAGE - The organic electroluminescent compounds have high luminous efficiency and excellent color purity and life property of material, are advantageous in that they can be employed to manufacture organic light emitting diodes having excellent operation life.    DETAILED DESCRIPTION - An organic electroluminescent anthracene compound of formula (I) or (II) is new.    R1 and R2=(1-60C)alkyl, (2-60C)alkenyl, (2-60C)alkynyl, (3-60C)cycloalkyl, (4-60C)tricycloalkyl, (7-60C)bicycloalkyl, (6-60C)aryl or (4-60C)heteroaryl (all optionally substituted by at least one deuterium, (1-60C)alkyl, (1-60C)alkoxy, halo, tri(1-60C)alkylsilyl, di(1-60C)alkyl(6-60C)arylsilyl, tri(6-60C)arylsilyl, cyano, (6-60C)aryl, (6-60C)aryl(1-60C)alkyl or (6-60C)aryl(1-60C)alkoxy), H, deuterium, 5- or 6-membered heterocycloalkyl containing at least one heteroatom of N, O or S, spirobifluorenyl, halo, cyano, (1-60C)alkoxy, tri(1-60C)alkylsilyl, di(1-60C)alkyl(6-60C)arylsilyl or tri(6-60C)arylsilyl;    Ar1-Ar4=5- or 6-membered heteroaryl containing 1-4 heteroatom of N, O or S.
