METALLIC COMPOUND AND ORGANIC ELECTROLUMINESCENCE DEVICE COMPRISING THE SAME

摘要

The present invention relates to a light emitting metallic compound of Chemical Formula 1 and an organic electroluminescence device including the compound. In the Chemical Formula 1 , M is selected from Ir, Pt, Rh, Re, and Os, m is 2 or 3, n is 0 or 1 , the sum of m and n is 3, provided that the sum of m and n is 2 when M is Pt. X is an N or P atom, Y is S, O, or Se, and Z is SiR⁵R⁶, CR⁵R⁶, PR⁵, S, SO₂, carbonyl, or NR⁵, and L² is represented by Chemical Formulae 2, 3, or 4.
