| abstract |
The present invention relates to an organometallic complex exhibiting high-quality blue color and high stability and heat resistance, and an organic electroluminescent device using the same, which provides a novel organometallic complex having a structure of any one of Chemical Formulas 2 to 5. The present invention also includes a first electrode having a high work function, a second electrode having a low work function, and the organometallic complex, and including at least one organic compound layer positioned between the first and second electrodes. It provides an organic electroluminescent device.n n n [Formula 2]n n n n n n n n [Formula 3]n n n n n n n n [Formula 4]n n n n n n n n [Formula 5]n n n n n n n n Wherein M 1 is Li, Na or K, M 2 is the same or different divalent metal, R 1 to R 9 may be the same or different, hydrogen or substituted or unsubstituted carbon of 1 to 10 Alkyl, aryl, heteroaryl or fused ring group, X is O or S. |
