Document Type and Number:
Japanese Patent JP4574358
Kind Code:
B2
Abstract:
(Object) The present invention provides a novel phosphorescent compound by synthesizing an orthometallated complex by using easy-synthesized ligands. Further, the invention provides an electroluminescent device having high luminous efficiency by using the phosphorescent compound. Moreover, the invention provides a light-emitting device operating at a low voltage by using the electroluminescent device. (Solution Method) According to the invention, a phosphorescent compound represented by general formula Äformula 1Ü is synthesized. Further, an electroluminescent device containing the phosphorescent compound is formed. In order to generate phosphorescent emission further efficiently, a heavy metal is preferably used as a central metal from the perspective of heavy atom effects. Therefore, one feature of the present invention is that the central metal M in the foregoing general formula Äformula 1Ü is iridium or platinum.
