Carbazole derivative, light-emitting element material and organic semiconductor material |
摘要 |
An object is to provide a novel carbazole derivative that has an excellent carrier-transport property and can be suitably used for a transport layer or as a host material of a light-emitting element. Another object is to provide an organic semiconductor material and a light-emitting element material each using the carbazole derivative. As the carbazole derivative that can achieve the above objects, a carbazole derivative in which a carbazolyl group whose either 2- or 3-position of carbazole is substituted by the 4-position of a dibenzothiophene skeleton or a dibenzofuran skeleton is bonded to aromatic hydrocarbon that has 14 to 70 carbon atoms and includes a condensed tricyclic ring, a condensed tetracyclic ring, a condensed pentacyclic ring, a condensed hexacyclic ring, or a condensed heptacyclic ring has been able to be synthesized. |
