Title:
POLYNUCLEAR ORGANOMETALLIC COMPLEXES, ORGANIC EL DEVICES AND ORGANIC EL DISPLAYS
Document Type and Number:
WIPO Patent Application WO/2004/069800
Kind Code:
A1
Abstract:
The invention provides organic EL devices which are made by using polynuclear organometallic complexes as the luminescent material and are excellent in lifetime, luminous efficiency, and so on, specifically an organic EL device comprising a positive electrode, a negative electrode, and an organic thin film placed between the electrodes, wherein the organic thin film contains a polynuclear organometallic complex which is composed of Group IB metal atoms, ligands each having at least one &pgr -conjugated moiety and coordinating to the metal atoms, and halogen atoms connecting the metal atoms by bridging. It is preferable that the polynuclear organometallic complex be one represented by the structural formula (1).
