  • Publication number: 20240306493
    Abstract: An object of one embodiment of the present invention is to provide a novel organic compound. The organic compound is a triarylamine derivative. The triarylamine derivative has an aryl group including a skeleton in which a naphthyl group is bonded to a naphthylene group. The other two aryl groups are each independently a phenyl group, a biphenyl group, or a terphenyl group. These groups may each have a substituent. As the substituent, an alkyl group having 1 to 6 carbon atoms or a cycloalkyl group having 3 to 6 carbon atoms can be selected.
