ABSTRACT:
Provision of a novel platinum complex which is useful as a material for a light-emitting device of good light emission characteristic and light emission efficiency, and a novel light-emitting material that may be utilized in various fields.A platinum complex represented by the following general formula (1):(in which two rings of ring A, ring B, ring C, and ring D represent nitrogen-containing heterocyclic rings which may have a substituent and the remaining two rings of them represent aryl rings or hetero aryl rings which may have a substituent, the ring A and the ring B, the ring A and the ring C or/and the ring B and the rind D may form condensed rings. Two of X1, X2, X3, and X4represent nitrogen atoms coordination bonded to a platinum atom and the remaining two of them represent carbon atoms or nitrogen atoms. Q1, Q2, and Q3each represents a bond, oxygen atom, sulfur atom or bivalent group, two of Z1, Z2, Z3, and Z4represent coordination bonds, and the remaining two of them represent covalent bonds, oxygen atoms or sulfur atoms), and a light-emitting device containing the platinum complex.
