    摘要: (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 [formula 1] 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 [formula 1] is iridium or platinum.

    摘要: A layer included in an electroluminescent element is required to be thickened to optimize light extraction efficiency of the electroluminescent element and to prevent short-circuit between electrodes. However, in a conventional element material, desired light extraction efficiency cannot be accomplished since drive voltage rises or power consumption is increased as the element material is thickened. A composite is formed by mixing a conjugated molecule having low ionization potential and a substance having an electron-accepting property to the conjugated molecule. A composite layer included in an element is formed using the composite as an element material. The composite layer is arranged between a first electrode and a light emitting layer or between a second electrode and a light emitting layer. The composite layer has high conductivity; therefore, drive voltage does not rise even if a film thickness is increased. Thus, an electroluminescent element which can prevent short-circuit of an electrode can be provided.

    摘要: A phosphorescent compound is formed by synthesizing an orthometallated complex by using easily-synthesized ligands. An electroluminescent device having high luminous efficiency uses the phosphorescent compound. Moreover, a light-emitting device operating at a low voltage uses the electroluminescent device. A phosphorescent compound represented by general formula [formula 1] is synthesized. Further, an electroluminescent device containing the phosphorescent compound is formed. In order to generate phosphorescent emission more 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 below general formula [formula 1] is iridium or platinum
