<p>Disclosed is a metal complex represented by the following formula (1). (1) (In the formula, M represents a metal atom; R1-R8 respectively represent a hydrogen atom, a halogen atom or a monovalent group; or alternatively R3 and R4, or R5 and R6 may combine together to form a ring. In this connection, at least one of R2 and R7 is a group represented by the following formula (2): (2) wherein m represents an integer of 1-3; n represents an integer of 0-2; and Z1-Z5 respectively represent a carbon atom or a nitrogen atom, provided that at least two of Z1-Z5 are nitrogen atoms. When one of Z1-Z5 is a carbon atom, the hydrogen atom bonded to the carbon atom may be substituted by a substituent. The moiety expressed by the following formula (3): (3) represents a monoanionic bidentate ligand. In the formula (3), Rx and Ry respectively represent an atom bonded to the metal atom M, namely a carbon atom, an oxygen atom or a nitrogen atom.)</p> |
