Abstract:
1. A composition comprising a metal complex represented by the following formula (1), and an organic compound, wherein a difference between an absolute value of a lowest unoccupied molecular orbital energy level of the metal complex and an absolute value of a lowest unoccupied molecular orbital energy level of the organic compound as calculated by a computational scientific approach wherein calculations are performed by a density functional method at B3LYP level with LANL2DZ basis function for the central metal atom and 6-31 g*basis function for atoms other than the central metal atom using Gaussian03 quantum chemical calculation program is less than 0.40 eV: wherein M is a metal atom of ruthenium, rhodium, palladium, osmium, iridium, or platinum, and R wherein R′ is a hydrogen atom, a halogen atom, and alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group, an arylalkylthio group, an acyl group, an acyloxy group, an amide group, an acid imide group, an imine residue, a substituted amino group, a substituted silyl group, a substituted silyloxy group, a substituted silylthio group, a substituted silylamino group, a monovalent heterocyclic group, a heteroaryloxy group, a heteroarylthio group, an arylalkenyl group, an arylalkynyl group, a substituted carboxyl group, or a cyano group; and a plurality of R′ may be the same or different, m is an integer of 1 to 3, and n is an integer of 0 to 2; a moiety represented by the following formula (3): represents a monoanionic bidentate ligand; and R
