摘要： To provide a novel carbazole compound that has an excellent carrier-transport property and can be used for a transport layer or as a host material in a light-emitting element. Further, to provide an organic semiconductor material and a material for a light-emitting element using the carbazole compound. A carbazole compound in which the 4-position of a dibenzothiophene skeleton or a dibenzofuran skeleton is substituted with the 2- or 3-position of a carbazole skeleton directly or via an arylene group can be synthesized. The carbazole compound is found to have a suitable carrier-transport property, a good film quality, and be used suitably as a material of a light-emitting element and an organic semicondcutor material. Note that nitrogen of the carbazole skeleton is substituted with any of a phenyl group, a biphenyl group, and a naphthyl group.

摘要： It is an object to provide a noble anthracene derivative, a light emitting element with a high luminous efficiency, and further a light emitting element with a long lifetime. It is another object to provide a light emitting device and electronic device with a long lifetime by using the light emitting element. An anthracene derivative represented by General Formula (1) is provided. Since the anthracene derivative represented by General Formula (1) has a high luminous efficiency, when the anthracene derivative is used for a light emitting element, the light emitting element can have a high luminous efficiency. Further, when the anthracene derivative represented by General Formula (1) is used for a light emitting element, the light emitting element can have a long lifetime.
