Document Type and Number:
WIPO Patent Application WO/2018/198973
Kind Code:
A1
Abstract:
Provided is a composition that is useful for producing a light-emitting element having excellent external quantum efficiency. Disclosed is a composition comprising at least two types of compounds represented by formula (C-1), and a phosphorescent compound, wherein at least one type of compound among said at least two types of compounds represented by formula (C-1) is a compound in which RC in the compound represented by formula (C-1) is a group represented by formula (C'-1). (In formula (C-1), ring R1C and ring R2C represent an aromatic hydrocarbon ring or an aromatic heterocycle. RC represents an oxygen atom, a sulfur atom, or a group represented by formula (C'-1).) (In formula (C'-1), ring R3C and ring R4C represent an aromatic hydrocarbon ring or an aromatic heterocycle.
