One aspect of the present invention is a light-emitting element having a layer containing an aromatic hydrocarbon and a metal oxide between a pair of electrodes. There is no particular limitation on the kind of aromatic hydrocarbon; however, an aromatic hydrocarbon having a hole mobility of 1 x 10-6 cm2 / Vs or more is preferable. Examples of such aromatic hydrocarbons include 2-tert-butyl-9,10-bis(2-naphthyl)anthracene, anthracene, 9,10-diphenylanthracene, tetracene, rubrene, perylene, 2,5,8,11-tetra(tert-butyl)perylene and so on. As the metal oxide, a metal oxide exhibiting electron-accepting properties for aromatic hydrocarbons is preferable. As such metal oxides, for example, molybdenum oxide, vanadium oxide, ruthenium oxide, rhenium oxide and the like are given.

The cyanine dye is a structural compound shown in formula (I) or a stereoisomer of a compound shown in formula (I), and the cyanine dye fluorescent probe has good specific biocompatibility, low cytotoxicity, small molecular weight, and is The advantage of small sample damage enables real-time observation of cell samples without being affected by intracellular pH.

The invention relates to a synthesis method of tetracene and pentacene compounds. A plurality of double-acetylene propanol carbonate compounds are prepared from simple and available phthalic dicarboxaldehyde compound and aryl acetylene by using addition reaction of an alkynyl lithium reagent. The double-acetylene propanol carbonate compounds can react with an organic boronic acid in series in the presence of a catalytic amount of palladium reagent, so as to further synthetize the tetracene and pentacene compounds at good to excellent yield. The method has the characteristics of being available in raw materials, simple to operate, mild in condition, convenient and fast, excellent in yield and the like, and aryl and alkyl can be effectively led to skeletons of tetracene and pentacene by using the method.
