Paragraph 0208-0209, (2020/07/14)
PROBLEM TO BE SOLVED: To provide: an organic compound excellent in luminous efficiency and color purity and applicable to an emission layer of an organic light emitting diode; an organic light emitting diode and an organic light emitting device that include the compound. SOLUTION: Disclosed is an organic compound with substituted aromatic functional groups at specific positions of a benzofluorenocarbazole core, represented by the formula in the figure. The organic compound realizes blue emission having high color purity, has a narrow Stokes shift, and has a very broad overlapping area of absorption wavelengths of the organic compound and emission wavelengths of a delayed fluorescent material.
