MATERIAL FOR LIGHT-EMITTING ELEMENT AND LIGHT EMITTING ELEMENT
摘要:
A material for a light-emitting element comprising a pyrene compound represented by the general formula (1): (1) wherein R1 to R10 independently represent a specific functional group, provided that at least one of R1 to R10 represents a substituent represented by the general formula (2): (2) where R11 to R14 independently represent a specific functional group, provided that any one of R11 to R14 is used for the single bonding to the pyrene backbone; X1 represents any one of the groups shown in the general formula (3) below; and Y1 to Y4 are independently selected from a nitrogen atom and a carbon atom, provided that at least one of Y1 to Y4 is a nitrogen atom and at least one of Y1 to Y4 is a carbon atom and, when it is a nitrogen atom, the nitrogen atom has no substituent attached thereon: (3) where R15 represents a specific functional group. By using this material, a light-emitting device having higher light-emitting efficiency and excellent durability can be provided.
