Metal coordination compound, luminescence device and display apparatus |
摘要 |
<p>An electroluminescence device having a layer containing a specific metal coordination compound is provided. The metal coordination compound is represented by formula (1) below: MLmL'n wherein M is a metal atom of Ir, Pt, Rh or Pd; L and L' are mutually different bidentate ligands; m is 1, 2 or 3 and n is 0, 1 or 2 with the proviso that m+n is 2 or 3; a partial structure MLm is represented by formula (2) shown below and a partial structure ML'n is represented by formula (3) or (4) shown below: <CHEM> The metal coordination compound of the formula (1) is characterized by having at least one aromatic substituent for at least one of CyN1, CyN2, CyC1 and CyC2. The metal coordination compound having the aromatic substituent is effective in providing high-efficiency luminescence, long-term high luminance, and less deterioration by current passing.</p> |
