A composite material including an organic compound and an inorganic compound and having a high carrier-transport property is provided. A composite material having a high carrier-injection property to an organic compound is provided. A composite material in which light absorption due to charge transfer interaction is unlikely to occur is provided. A light-emitting element having high emission efficiency is provided by including the composite material. A light-emitting element having a low drive voltage is provided. A light-emitting element having a long lifetime is provided. A composite material including a heterocyclic compound having a dibenzothiophene skeleton or a dibenzofuran skeleton and an inorganic compound exhibiting an electron-accepting property with respect to the heterocyclic compound is provided.

Page/Page column 44-45, (2012/07/13)
Provided is a benzo[b]naphtho[1,2-d]furan compound having a wide band gap which gives excellent color purity of blue. Further provided are a light-emitting element, a light-emitting device, and an electronic device each of which uses the benzo[b]naphtho[1,2-d]furan compound and is highly reliable. A benzo[b]naphtho[1,2-d]furan compound represented by a general formula (G1) is provided. In the general formula (G1), An represents an anthryl group represented by a general formula (An-1) or (An-2) below, α1 and α2 separately represent a substituted or unsubstituted phenylene group represented by any one of general formulae (α-1) to (α-3) below, and R1 to R9 separately represent either hydrogen or an alkyl group having 1 to 4 carbon atoms. Further, in the general formula (G1), n and m separately represent 0 or 1.

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.
