Patent ID: 8329929

Claim:
A metal complex represented by the following formula (1): wherein R 1 to R 6 each independently represent a hydrogen atom or a substituent; R 1 and R 2 , R 2 and R 3 , R 4 and R 5 , and/or R 5 and R 6 may be linked to each other to form a ring; and Y 1 and Y 2 each independently represent any one of the following groups: wherein R α represents a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms; P 1 represents a group of atoms necessary for forming a heterocyclic ring together with Y 1 and the two carbon atoms at a position adjacent to Y 1 ; P 2 represents a group of atoms necessary for forming a heterocyclic ring together with Y 2 and the two carbon atoms at a position adjacent to Y 2 ; P 1 and P 2 may be linked to each other, to form a ring; m represents 1 or 2; when m is 1, M represents aluminum, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, germanium, zirconium, niobium, molybdenum, ruthenium, rhodium, palladium, silver, cadmium, indium, tin, antimony, tantalum, tungsten, rhenium, osmium, iridium, platinum, or gold; when m is 2, two M's may be the same as or different from each other, and M represents a transition metal element belonging to Groups 3 to 9 described in the periodic table; X represents a counter ion or a neutral molecule; n represents the number of X's in the complex, and an integer of 0 or more; when a plurality of X's are present, the X's may be the same as or different from each other; and Q 1 and Q 2 each independently represent an aromatic heterocyclic group.
