摘要

A carbazole compound in which the 2-position of a dibenzofuran skeleton or a dibenzothiophene skeleton is bonded to the 3-position of a carbazole skeleton and nitrogen of the carbazolyl group is bonded to the 9- or 10-position of an anthracene skeleton directly or via a phenylene group was able to be synthesized. It was found out that the carbazole compound has an excellent carrier-transport property, favorable film quality, and a wide band gap, and can be suitably used as a light-emitting element material and an organic semiconductor material.
