Abstract:
1. A complex represented by Chemical Formula 1: wherein M represents cobalt or chrome; L represents a ligand represented by Chemical Formula 3;  A represents an oxygen or sulfur atom; R G represents a nitrogen or phosphorus atom; R R X′ represents an oxygen atom, sulfur atom or N—R (wherein R represents a Hydrogen radical; or a (C1-C20)alkyl, (C2-C20)alkenyl, (C1-C15)alkyl(C6-C20)aryl or (C6-C20)aryl(C1-C15)alkyl radical with or without at least one of halogen, nitrogen, oxygen, silicon, sulfur and phosphorus atoms a represents 1, 2 or 3, wherein when a is 1, L includes at least two of the chemical formulas 2a, 2b, and 2c, and when a is 2 or 3, L(s) are the same or different, and are optionally linked to each other to be chelated to the metal as a bidentate or tridentate ligand, with the proviso that at least one L includes at least one of chemical formulas 2a, 2b, and 2c and the total number of chemical formulas 2a, 2b and 2c contained in L(s) represent 2 or more; X wherein R represents methyl or H; and R′ is selected from H and nitro (—NO b and c satisy the condition of “(b+c)=(total number of the chemical formulas 2a, 2b, and 2c contained in L)+[(oxidation number of metal)−(a)]”.
