Title:
METAL COORDINATION COMPOUND AND ELECTROLUMINESCENCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/000661
Kind Code:
A1
Abstract:
A metal coordination compound having a basic structure expressed by general formula MLmL’n (1) [wherein M represents a metal atom of Ir, Pt, Rh, or Pd, L and L’ represent mutually different bidentate ligands, m is 1, 2, or 3, n is 0, 1, or 2, and m &plus n is 2 or 3]. The basic structure includes a partial structure in which at least one bidentate ligand L is condensated through an alkylene group having 2−10 carbon atoms. An electroluminescence device having a cathode, an anode, and a plurality of organic thin films between the cathode and anode is also disclosed. At least one of the organic thin films is a luminescence layer made of a host material and luminance molecules of a metal coordination compound having a structure expressed by general formula (1) and mixed in the host material as a guest material. The electroluminescence device emits light at high efficiency and maintains a high luminance stably for a long term.
