Abstract

The present disclosure provides a composition that contains an iridium complex and an isomer of the iridium complex, in which the amount of the isomer of the iridium complex is decreased. The iridium complex is a homo-N-trans (HNT) iridium complex having an iridium atom, and a first ligand, a second ligand, and a third ligand that are bonded to the iridium atom. The isomer has an iridium atom, a fourth ligand, a fifth ligand, and the third ligand. The composition ratio of the isomer relative to a total of the iridium complex and the isomer is 1.0% or less.
