Abstract
An object is to provide an azoline ring-containing compound which achieves characteristics required for an organic EL element, such as a driving voltage, a quantum efficiency, and element lifetime in a well-balanced manner, and particularly can obtain a high quantum efficiency, for example, in a case where the azoline ring-containing compound is used for the organic EL element. The above object is achieved by an azoline ring-containing compound represented by the following general formula (1).In formula (1), φ represents an m-valent group derived from an aromatic hydrocarbon having 6 to 40 carbon atoms or the like, Y represents —O—, —S—, or >N—Ar, R1 to R5 each represent a hydrogen atom or an alkyl having 1 to 4 carbon atoms, and L represents a phenylene group or the like.
