An object of the present invention is to provide a red light emitting element material with high color purity and a light emitting element using the red light emitting element material. The present invention is a light emitting element material including a compound which is expressed by following general formula (A) and a light emitting element using the compound. In the following general formula (A), at least two of R 1 , R 2 , and R 3 each independently represents an aryl group or heterocyclic group, and at least one of the R 1 , R 2 , and R 3 contains a group expressed by following general formula (B). In the general formula (B), R 4 represents a heterocyclic group or electron attracting group, R 5 represents a hydrogen atom or electron attracting group, R 6 , R 7 , and R 8 each independently represents a hydrogen atom or substituent, and m represents 0, 1, or 2. However, in a case in which only one group expressed by the general formula (B) is contained in the general formula (A), R 4 and R 5 are not cyano groups at the same time. When R 5 is a hydrogen atom, R 4 represents a heterocyclic group which has aromatic rings and is formed from 3 to 7 rings. |
