Abstract:
A composition is provided in which a phosphorescent compound represented by formula (1) and a host material are blended with each other. The amount of chlorine atoms contained as impurities in the phosphorescent compound is 3.5 ppm by mass or less with respect to the total amount of solid contents blended in the composition In Formula (1), M 1  represents an iridium atom; n 1  represents an integer of 1 or more, n 2  represents an integer of 0 or more, n 1 +n 2  is 2 or 3; E 1  and E 2  represent a carbon atom or a nitrogen atom; R 1  ring represents a 5-membered aromatic heterocyclic ring and R 2  ring represents an aromatic hydrocarbon ring; A 1 -G 1 -A 2  represents an anionic bidentate ligand; A 1  and A 2  represent a nitrogen atom; and G 1  represents a single bond.

Claim (Index 11):
A phosphorescent compound represented by formula (1),\n wherein the amount of chlorine atoms contained as impurities is 15 ppm by mass or less with respect to the total amount of the phosphorescent compound: wherein, M 1  represents a rhodium atom, a palladium atom, an iridium atom, or a platinum atom; n 1  represents an integer of 1 or more, n 2  represents an integer of 0 or more, and n 1 +n 2  is 2 or 3; when M 1  is a rhodium atom or an iridium atom, n 1 +n 2  is 3; when M 1  is a palladium atom or a platinum atom, n 1 +n 2  is 2; E 1  and E 2  each independently represent a carbon atom or a nitrogen atom, provided that at least one of E 1  and E 2  is a carbon atom; R 1  ring represents a 5-membered aromatic heterocyclic ring, the ring may have a substituent; when there are a plurality of the substituents, they may be the same or different, or may be bonded to each other to form a ring together with the atoms to which they are bonded; when there are a plurality of R 1  rings, they may be the same or different; R 2  ring represents an aromatic hydrocarbon ring or an aromatic heterocyclic ring, and these rings each may have a substituent; when there are a plurality of the substituents, they may be the same or different, or may be bonded to each other to form a ring together with the atoms to which they are bonded; when there are a plurality of R 2  rings, they may be the same or different; the substituent that the R 1  ring may have and the substituent that the R 2  ring may have may be bonded to each other to form a ring together with the atoms to which they are bonded; A 1 -G 1 -A 2  represents an anionic bidentate ligand; A 1  and A 2  each independently represent a carbon atom, an oxygen atom, or a nitrogen atom, and these atoms each may be atoms constituting a ring; G 1  represents a single bond or an atomic group constituting the bidentate ligand together with A 1  and A 2 ; and when there are a plurality of A 1 -G 1 -A 2 , they may be the same or different.
