    摘要： The present invention discloses a novel compound of Formula 1, and an organic electroluminescent device using the same. In Formula 1, X and Y independently represents an aromatic or a hetero aromatic hydrocarbon having a carbon number of from 5 to 10. Ar1 to Ar7 each independently represents an unsubstituted or substituted aromatic hydrocarbon having a carbon number of from 4 to C12, or an unsubstituted or substituted condensed polycyclic aromatic hydrocarbon having a carbon number of from 4 to 12; Ar1 to Ar7 can form an annulated or fused aromatic ring system with the adjacent aromatic hydrocarbons. When the compound of Formula I is used in the device, high luminous efficiency, longer lifetime and low driving voltage can be achieved.
