Title:
DIAMANTANE COMPOUND, ORGANIC ELECTROLUMINESCENCE ELEMENT MATERIAL, AND ORGANIC ELECTROLUMINESCENCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/120152
Kind Code:
A1
Abstract:
Provided are: a diamantane compound that makes it possible to produce an organic electroluminescence element that achieves excellent light-emission efficiency characteristics or, more preferably, excellent drive voltage characteristics and excellent light-emission efficiency characteristics; and an organic electroluminescence element material that includes the diamantane compound. Also provided is an organic electroluminescence element that achieves high-level light-emission efficiency characteristics or, more preferably, high-level drive voltage characteristics and high-level light-emission efficiency characteristics. The present invention provides a diamantane compound that includes a group represented by formula (1) and a group represented by formula (2). (In formula (1), the carbon atoms of the diamantane ring may be substituted with a C6–12 aryl group. In formula (1), * indicates a bond. a represents an integer from 1 to 6.) (In formula (2), Ar indicates (i) an optionally substituted C6–60 aromatic hydrocarbon group, (ii) an optionally substituted C3–60 heteroaromatic group, or (iii) a combination of (i) and (ii). However, when Ar has a total of at least 8 carbon atoms and is only the C6–60 aromatic hydrocarbon group of (i), Ar has a total of at least 13 carbon atoms. In formula (2), * indicates a bond. b represents an integer from 1 to 6.)
