    摘要： The present invention relates to novel organic electroluminescent compounds, and organic electroluminescent devices comprising the same as electroluminescent material. Specifically, the organic electroluminescent compounds according to the invention are characterized in that they are represented by Chemical Formula (1): wherein, L1 is a substituent selected from the following structures; A and B independently represent a chemical bond, or a substituent selected from the following structures; m and n independently represent an integer from 0 to 4; provided that, if represents both X1 and X2 represent NR33, and both Y1 and Y2 represent a chemical bond, then R33 does not represent hydrogen or (C1-C5)alkyl.The organic electroluminescent compounds according to the invention exhibit high luminous efficiency in blue color and excellent life property of material, so that an OLED having very good operation life can be prepared therefrom.
