Title:
DEUTERIDE AND ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/255243
Kind Code:
A1
Abstract:
Provided are: an organic EL element having low driving voltage, high efficiency, and a long service life and useful for practical use; and a deuteride suitable for the organic EL element. The deuteride has such a property that the deuteration rate of hydrogen atoms on two carbazole rings in a compound represented by general formula (1) is 30% or more and the deuteration rate of hydrogen atoms on aromatic rings respectively in Ar1 and Ar2 is 40% or more. (In the formula, Ar1 and Ar2 independently represent a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 carbon atoms, or a substituted or unsubstituted linked aromatic group having such a structure that two to five aromatic rings as mentioned above are linked together, in which, when aromatic hydrocarbon groups are linked, the aromatic hydrocarbon groups may be the same as or different from each other.)
