PROBLEM TO BE SOLVED: To provide a diarylethene derivative and an organic electroluminescent device prepared by using the same. SOLUTION: The organic light emitting compound is a diarylethene derivative namely a compound 2 prepared, for example, according to the formula as shown in the figure.

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. COPYRIGHT: (C)2005,JPO&NCIPI
