Abstract
The present invention is to provide a light emitting material, for an organic EL device, exhibiting higher light emitting efficiency, and particularly, to provide a blue light emitting material, wherein the light emitting material comprises a compound of the following General Formula (1): X is an aryl group including a tertiary amine structure, and Y is a phenyl group having an alkyl or aryl substituent at one ortho position.
Claims8
A compound of the following General Formula (1):
- in General Formula (1), X and Y represent substituents, X and Y are not the same as each other,
- X is a substituent of General Formula (2), and Y is a phenyl group having an alkyl or aryl substituent at one ortho position:
- in General Formula (2),
- R2 to R5 are each independently hydrogen or a substituent optionally independently mono-, di-, tri-, tetra-, or penta-substituted;
- R1 and R6 are each independently hydrogen, or a substituent optionally independently mono-, di-, tri-, tetra-, or penta-substituted;
- or R1 and R2, and R5 and R6 are each independently bonded with each other, respectively, through a single bond, an alkylene, an arylene, —O—, —S—, SiR11R12, —NR—, or —BR—;
- or R3 and R4 are boned with each other through an alkylene, an arylene, —O—, —S—, SiR11R12, —NR—, or —BR—
- R11 and R12 are each independently an alkyl group or an aryl group;
- R is a hydrogen atom, an alkyl group, or an aryl group;
- Ra and Rb are each independently a substituent optionally independently mono-, di-, tri-, tetra-, or penta-substituted, or not present, Rc is a substituent optionally mono-, di-, tri-, or tetra-substituted, or not present;
- the substituent is independently an alkyl group or an aryl group;
- and
- * represents a position which is bonded to the anthracene ring on the left side of General Formula (1) at any one of the ortho, meta, or para positions with respect to nitrogen atom of the triphenylamine of General Formula (2).
