The present invention is a light-emitting device material characterized by containing a pyrene compound represented by the following general formula (1):
wherein R1 to R10 are specific functional groups, provided that at least one of the R1 to R10 is a substituent represented by the following general formula (2):
wherein R11 to R14 are specific functional groups, provided that any one of the R11 to R14 is used for a single bond with a pyrene skeleton; X1 is a group represented by the following general formula (3):
wherein R15 is a specific functional group; and
Y1 to Y4 is selected from among a nitrogen atom and a carbon atom, provided that at least one of the Y1 to Y4 is a nitrogen atom and at least one thereof is a carbon atom, and no substituents exist on the nitrogen atom in the case of the nitrogen atom.
This material provides a light-emitting device having high luminous efficiency and excellent durability.
