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 9):
The composition according to  claim 1 , wherein the host material is a compound represented by formula (H-1): wherein, Ar H1  and Ar H2  each independently represent an aryl group or a monovalent heterocyclic group, and these groups each may have a substituent; n H1  and n H2  each independently represent 0 or 1; when there are a plurality of n H1 , they may be the same or different; the plurality of n H2  may be the same or different; n H3  represents an integer of 0 or more; L H1  represents an arylene group, a divalent heterocyclic group, or a group represented by \u2014[C(R H11 ) 2 ]n H11 \u2014, and these groups each may have a substituent; when there are a plurality of L H1 , they may be the same or different; n H11  represents an integer of 1 or more and 10 or less; R H11  represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group, or a monovalent heterocyclic group, and these groups each may have a substituent; the plurality of R H11  may be the same or different, or may be bonded to each other to form a ring together with the carbon atom to which they are bonded; L H2  represents a group represented by \u2014N(-L H21 -R H21 )\u2014; when there are a plurality of L H2 , they may be the same or different; L H21  represents a single bond, an arylene group, or a divalent heterocyclic group, and these groups each may have a substituent; and R H21  represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, or a monovalent heterocyclic group, and these groups each may have a substituent.
