PROBLEM TO BE SOLVED: To provide a compound for a light-emitting material having high light-emitting efficiency even in a solid state, and to provide the light-emitting material using the compound, and an organic EL element.SOLUTION: A bis(diarylamino)phthalic acid derivative, preferably a bis(diarylamino)phthalic acid ester is used as a light-emitting material. Further, the light-emitting material contains a host compound and a dopant compound, and preferably contains the bis(diarylamino)phthalic acid derivative as the dopant compound. A content of the bis(diarylamino)phthalic acid derivative in the light-emitting material is preferably 0.1 to 50 pts.wt. with respect to 100 pts.wt. of the host compound. |
