Title:
ORGANIC METAL COMPLEX, ORGANIC ELECTROLUMINESCENT ELEMENT, METHOD FOR MANUFACTURING SAME, DISPLAY DEVICE AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/119200
Kind Code:
A1
Abstract:
The objective of the present invention is to provide: an organic metal complex which has both good stability and good luminescent properties at the same time and is capable of improving the luminous efficiency and luminance life of an element; an organic electroluminescent element which contains this organic metal complex; a method for manufacturing this organic electroluminescent element; a display device; and a lighting device. An organic metal complex according to the present invention has a structure which contains a group 8-11 metal of the periodic table (for example, iridium or the like) as a central metal, and wherein bidentate ligands, which are linked with each other through a crosslinking group, are coordinated. Each ligand is configured from an aromatic hydrocarbon ring or an aromatic heterocyclic ring (for example, 2-phenylimidazole or the like), and a divalent or higher-valent heteroatom (for example, an oxygen atom, a nitrogen atom, a sulfur atom or the like), to which a crosslinking group is linked, is bonded at the ortho position with respect to the coordination bond between the metal and the ligand. An organic electroluminescent element according to the present invention contains this organic metal complex in an organic layer, and is formed by a wet process method. A display device and a lighting device according to the present invention are provided with this organic electroluminescent element.
