Paragraph 0289-0291; 0724-0726, (2016/10/10)
The present invention relates to an organic light emitting compound adopted to an organic electroluminescent device. The organic light emitting compound is represented by chemical formula 1 or chemical formula 2. In the case of adopting the organic light emitting compound as a phosphorescence host compound in a hole transport functional layer or a luminous layer, an organic electroluminescent device having excellent luminous characteristics such as operating voltage, brightness, long lifespan, etc.

Page/Page column 39, (2010/02/13)
Provided are an aromatic amine compound represented by the following Formula (1) and an organic electroluminescent element which has at least one organic thin film layer containing the above aromatic amine derivative in the form of a single component. The organic electroluminescent element described above has a high luminescent efficiency even at a low voltage and a long life. It can emit blue light even at high temperatures. In Formula (1), Ar1 and Ar2 each represent naphthyl and the like; Ar3 to Ar6 each represent phenyl, naphthyl, phenanthryl and the like; Ar7 to Ar10 each represent 1,4-phenylene and the like; L represents a single bond and the like; provided that the conditions of (1) and/or (2) are satisfied:(1) at least one of Ar3 to Ar6 is a condensed aryl group having 10 to 50 nuclear carbon atoms and(2) at least one of Ar1 and Ar2 is a condensed aryl group having 12 to 50 nuclear carbon atoms.
