1. A method for synthetizing an organic metal complex having a structure represented by Formula (1), the method comprising:
replacing substituents RX and RX′ in an organic metal complex having a structure represented by Formula (2) with substituents RB and RB′, respectively, in an organic metal complex having a structure represented by Formula (1): where the ring formed by A11 to A16 is an aromatic hydrocarbon ring or a heteroaromatic ring; A11 to A16 each independently represent a carbon or nitrogen atom; A11 forms a covalent bond with a central metal M; the ring formed by B11 to B15 is a heteroaromatic ring; B11 and B12 each independently represent a carbon or nitrogen atom, B13 to B15 each independently a carbon, nitrogen, or oxygen atom, and at least two of B11 to B15 are a nitrogen atom; B11 forms a coordination bond with the central metal M; Ra represents a substituent and p represents an integer of 0 to 4; Rb represents a substituent and q represents an integer of 0 to 3; if two or more Ra's are present, Ra's may be identical to or different from one another; if two or more Rb's are present, Rb's may be identical to or different from one another; Ra's are optionally bonded together to form a ring structure, and Rb's are optionally bonded together to form a ring structure; Ra and Rb are optionally bonded together to form a ring structure; RB and RB′ each independently represent a hydroxy group or a substituent containing a nitrogen, sulfur, or phosphorus atom having a lone pair; r and r′ each independently represent an integer of 0 or more and satisfy the relation: r+r′≧1, and p, q, r, and r′ satisfy the following relations: 0≦p+r′≦4 and 0≦q+r≦3; M represents iridium or platinum; L represents a monoanionic bidentate ligand; and n represents an integer of 1 to 3, m represents an integer of 0 to 2, and the sum of m and n is 2 or 3; where RX and RX′ respectively represent substituents replaceable with RB and RB′; A11 to A16, B11 to B15, Ra, p, Rb, q, r, r′, M, L, n, and m are the same as those defined in Formula (1); and the positions of Ra, Rb, RB, and RB′ in Formula (1) are the same as those of Ra, Rb, RX, and RX′, respectively, in Formula (2). |
