Abstract: PROBLEM TO BE SOLVED: To provide an organic electroluminescent element which is improved in characteristics, such as light emission efficiency of the phosphorescent material and color purity.
SOLUTION: The organic electroluminescent element is provided with a host, a dopant of phosphorescent molecule, and an EML receiving energy from the host, directly trapping energy and transmitting the energy to the dopant or composed of a fluorescent supporter emitting light of itself. The light-emitting spectrum of the fluorescent supporter partially or wholly overlaps the absorbing spectrum of the phosphorescent molecule. The organic electroluminescent element is improved in the light-emitting efficiency and in the color purity feature, as compared with conventional organic electroluminescent elements having an EML composed of a phosphorescent dopant and a host. A system, such as this, is particularly useful for blue color light-emitting elements.

Abstract: PROBLEM TO BE SOLVED: To provide a luminescent material which can emit a light from the blue region to the red region through the triplet MLCT(Metal-to-Ligand Charge-Transfer) and to provide an organic electroluminescence element using this. SOLUTION: A luminescent material emitting a phosphorescence is synthesized by bonding an organic metal complex to the side chain of a polysilsesquioxane. This luminescent material can be used when an organic film of an organic electroluminescence element is formed. This luminescent material emits a light in the wavelength range of 430-650 nm and is excellent in color purity and light emitting efficiency characteristics. COPYRIGHT: (C)2005,JPO&NCIPI
