PROBLEM TO BE SOLVED: To provide a compound for an organic EL device and an organic EL device which is capable of emitting light of sufficient luminance, particularly at a long wavelength, and has excellent light-emitting performance and excellent durability over a long period of time. An element is provided. A compound for an organic EL device having a basic skeleton represented by the following formula (I) and an organic EL device using the same. Embedded image (In the above formula (I), R 1 , R 2 , R 3 and R 4 each represent a substituted or unsubstituted aryl group or alkenyl group. R 5 , R 6 , R 7 and R 8 each represent hydrogen. And at least two of R 1 to R 4 are two or more rings, an aryl group having an aryl group, an amino group, an alkenyl group, an aryloxy group and a heterocyclic group as a substituent, or an alkenyl group. When two or more substituents are a monocyclic aryl group, the group further has a substituent, and when the substituent is an amino group, R 1 , R 2 , R 3 and R 4 At least two or more have a substituted or unsubstituted aryl group as a substituent.) |
