ABSTRACT:
A metal coordination compound having a basic structure represented by formula: MLmL′n(1), 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; wherein at least one bidentate ligand has a partial structure formed by condensation via an alkylene group having 2–10 carbon atoms, is provided. In an electroluminescence device composed of one or a plurality of organic films disposed between a cathode and an anode, at least one layer is a luminescence layer which is formed by incorporating luminescence molecules constituting the metal coordination compound having a structure of the formula (1) described above as a guest material in a host material thereby to provide an electroluminescence device producing luminescence at high efficiency and stably keeping a high luminance for a long period.
