    摘要： Disclosed is an organic EL element material represented by the following general formula (1):

    wherein, in the general formula (1), any one of X 1 to X 3 is a nitrogen atom, and others are methine groups; L 1 is a substituted or unsubstituted phenylene group, a substituted or unsubstituted naphthylene group, or substituted or unsubstituted anthrylene group; L 2 is single bond, a substituted or unsubstituted phenylene group, a substituted or unsubstituted naphthylene group, or a substituted or unsubstituted anthrylene group, in which when these groups are substituted, the substituent is an alkyl group or an alkoxy group; A is a phenyl group or a pyridyl group; and n is 0 or 1. An organic EL element excellent in luminance efficiency and durability life is provided.
