An object of the invention is to provide an organic EL device-forming compound and an organic EL device which produce light emission of satisfactory luminance, especially at long wavelength and are durable in that improved light emitting performance lasts for a long time. The object is attained by a compound having a basic skeleton represented by formula (I) and an organic EL device comprising the same. In formula (I), R1, R2, R3, and R4 each are a substituted or unsubstituted aryl or alkenyl group; R5, R6, R7, and R8 each are hydrogen; at least two of R1 to R4 are aryl groups which are at least bicyclic, aryl groups having aryl, amino, alkenyl, aryloxy or heterocyclic groups as substituents, or alkenyl groups, and when at least two substituents are monocyclic aryl groups, they further have substituents, and when the substituents are amino groups, at least two of R1, R2, R3, and R4 have substituted or unsubstituted aryl groups as substituents.
A compound for organic electroluminescent devices, having a basic skeleton represented by the following formula (I):
An organic electroluminescent device comprising a hole injecting electrode, an electron injecting electrode, and an organic layer disposed between the electrodes and including at least a light emitting layer, wherein
