Patent ID: 7736755

Claim:
An organic electroluminescent device comprising: a pair of electrodes; and at least one organic compound layer including a light emitting layer between the pair of electrodes, wherein the at least one organic compound layer contains a metal complex; wherein the metal complex is a compound represented by Formula (2) or (3): in Formula (2), M 21 and M 22 each independently represents a metal ion; Q 21 , Q 22 , Q 23 and Q 24 each independently represents an atom group coordinating with M 21 ; Q 25 , Q 26 , Q 27 and Q 28 each independently represents an atom group coordinating with M 22 ; L 21 , L 22 , L 23 , L 24 , L 25 and L 26 each independently represents a single bond or a connection group; L 27 is a carbon atom, a silicon atom, an aryl group, or a heteroaryl group; n 21 and n 22 each independently represents 0 or 1, provided that when n 21 is 0, a bond in which L 23 is interposed between Q 23 and Q 24 does not exist, and when n 22 is 0, a bond in which L 26 is interposed between Q 27 and Q 28 does not exist; M 21 -Q 21 bond, M 21 -Q 22 bond, M 22 -Q 25 bond and M 22 -Q 26 bond (dotted line) represent coordinate bonds; and M 21 -Q 23 bond, M 21 -Q 24 bond, M 22 -Q 27 bond and M 22 -Q 28 bond may each be a covalent bond, a coordinate bond or an ion bond, and in Formula (3), M 31 and M 32 each independently represent a metal ion; Q 31 , Q 32 , Q 33 and Q 34 each independently represents an atom group coordinating with M 31 ; Q 35 , Q 36 , Q 37 and Q 38 each independently represents an atom group coordinating with M 32 ; L 31 , L 32 , L 33 , L 34 , L 35 and L 36 each independently represents a single bond or a connection group; L 37 is a carbon atom, a silicon atom, an aryl group, or a heteroaryl group; n 31 and n 32 each independently represents 0 or 1, provided that when n 31 is 0, a bond in which L 33 is interposed between Q 33 and Q 34 does not exist, and when n 32 is 0, a bond in which L 36 is interposed between Q 37 and Q 38 does not exist; M 31 -Q 33 bond, M 31 -Q 34 bond, M 32 -Q 37 bond and M 32 -Q 38 bond (dotted line) represent coordinate bonds; and M 31 -Q 31 bond, M 31 -Q 32 bond, M 32 -Q 35 bond and M 32 -Q 36 bond each may be a covalent bond, a coordinate bond or an ion bond.
