摘要

The nitrogen atom of the carbazolyl group bonded to the 3-position of the carbazole skeleton at the 2-position of the dibenzofuran skeleton or the dibenzothiophene skeleton is bonded directly to the 9-position or the 10-position of the anthracene skeleton or via the phenylene group And the resulting carbazole compound could be synthesized. It has been found that the carbazole compound has good carrier transportability, film quality and wide band gap and can be suitably used as a material for a light emitting device or an organic semiconductor material.
