Paragraph 0225; 0227-0229, (2019/06/07)
A nitrogen-containing compound represented by Formula 1 (shown in the description) below may be included in a light emitting layer of an organic electroluminescence device. The resulting organic electroluminescence device may exhibit improved light emitting efficiency and may emit deep blue light: wherein, X 1 to X 13 are each independently CR 1 , CR 2 or N, at least one of X 1 to X 8 and at leastone of X 9 to X 13 is N, at least one of X 1 to X 13 is CR 2 , and R 2 is represented by Formula 2 (shown in the description).
Noble Compound Exhibiting Thermally Activated Delayed Fluorescence and Organic Light-Emitting device Using the Same
-
Paragraph 0064-0066, (2018/03/23)
The present invention relates to a novel compound which due to having little difference between a singlet energy state and a triplet energy state, exhibits a thermally activated delayed fluorescence by reverse intersystem crossing when heat is applied, that generates the singlet energy state from the triplet energy state; and to an organic light-emitting device which applies the same to a dopant of an organic light-emitting layer. Specifically, the present invention relates to a compound represented by chemical formula 1; and to an organic light-emitting device which applies the same to a dopant of an organic light-emitting layer, wherein in the chemical formula 1, R_1 and R_2 may be identical or different from each other, and are a pyridoindole group, a phenyl group, a carbazole group, a 9,9-dimethyl-9,10-dihydroacridine group, a 10H-phenothiazine group, or 10H-phenoxazine group, and R_3 is a methyl or phenyl group.COPYRIGHT KIPO 2017
