[EN] AN ORGANIC ELECTROLUMINESCENT COMPOUND AND AN ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME [FR] COMPOSÉ ÉLECTROLUMINESCENT ORGANIQUE ET DISPOSITIF ÉLECTROLUMINESCENT ORGANIQUE COMPRENANT CE COMPOSÉ
Provided is a composite material which makes it possible to provide a light-emitting element having at least one of the following characteristics by applying the composite material to the light-emitting element: low voltage driving, high emission efficiency, and a long life (high reliability). The composite material includes a hydrocarbon compound and an inorganic compound which exhibits an electron-accepting property with respect to the hydrocarbon compound. The hydrocarbon compound has a molecular weight of greater than or equal to 400 and less than or equal to 2000, where one or more aryl groups are bonded to a fluorene unit.
