ABSTRACT:
Provided is a light emitting material of which a light emitting device having high luminous efficiency and high stability and capable of being provided at a low cost can be formed. A light emitting material includes the following partial structural formula (1):wherein at least one of R1to R10represents a substituent except a hydrogen atom, a total number of benzene ring structures in R1to R10is 3 or more, and R1to R10include a trifluoromethyl group, or a linear, branched, or cyclic alkyl or alkoxyl group having 2 or more carbon atoms a hydrogen atom of which may be substituted by a halogen atom.
