    摘要: The subject of the present invention is to provide an emission material which contributes to high emission efficiency, low drive voltage, excellent heat resistance and long life in an organic electroluminescent device, particularly an emission material which is excellent in emission of blue color. Further, the subject is to provide an organic electroluminescent device using the above emission material. The above subjects can be achieved by an emission material represented by Formula (1) and an organic electroluminescent device comprising the same. wherein R1 to R7 are independently hydrogen, alkyl or cycloalkyl; Ar1 is one selected from the group consisting of non-condensed aryl having 6 to 50 carbon atoms, 2-naphthyl, 9-phenanthryl, 6-chrysenyl, 2-triphenylenyl, 2-fluorenyl, 9-carbazolyl, 2-thienyl and 2-benzothienyl; and Ar2 and Ar3 are independently non-condensed aryl having 6 to 50 carbon atoms, condensed aryl having 10 to 50 carbon atoms or heteroaryl having 2 to 50 carbon atoms.
