Abstract:
A transition metal complex having the formula: wherein c is a negative, neutral, or positive charge represented by âˆ’1 to âˆ’5, 0, or +1 to +5, inclusive, respectively; M is cobalt, iron, osmium, ruthenium, or vanadium; L1 is a substituted or an unsubstituted heterocyclic nitrogen-containing ligand; L2 is a negatively charged ligand; and L and Lâ€² are independently: wherein Râ€²1 is a substituted or an unsubstituted alkyl, alkenyl, or aryl; Ra and Rb are independently â€”H, â€”F, â€”Cl, â€”Br, â€”I, â€”NO2, â€”CN, â€”CO2H, â€”SO3H, â€”NHNH2, â€”SH, â€”OH, â€”NH2, or substituted or unsubstituted alkoxycarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkoxy, alkylamino, dialkylamino, alkanoylamino, arylcarboxamido, hydrazino, alkylhydrazino, hydroxylamino, alkoxylamino, alkylthio, alkenyl, aryl, or alkyl; Râ€²3, Râ€²4 are independently â€”H, â€”F, â€”Cl, â€”Br, â€”I, â€”NO2, â€”CN, â€”CO2H, â€”SO3H, â€”NHNH2, â€”SH, â€”OH, â€”NH2, or substituted or unsubstituted alkoxycarbonyl, alkylaminocarbonyl dialkylaminocarbonyl, alkoxy, alkylamino, dialkylamino, alkanoylamino, arylcarboxamido, hydrazino, alkylhydrazino, hydroxylamino, alkoxylamino, alkylthio, alkenyl, aryl, or alkyl, or a combination of Râ€²3 and Râ€²4 forms a saturated or unsaturated 5- or 6-membered ring; and Rc, and Rd are independently â€”H, â€”F, â€”Cl, â€”Br, â€”I, â€”NO2, â€”CN, â€”CO2H, â€”SO3H, â€”NHNH2, â€”SH, â€”OH, â€”NH2, or substituted or unsubstituted alkoxycarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkoxy, alkylamino, dialkylamino, alkanoylamino, arylcarboxamido, hydrazino, alkylhydrazino, hydroxylamino, alkoxylamino, alkylthio, alkenyl, aryl, or alkyl, or a combination of Rc and Rd forms a saturated or unsaturated 5- or 6-membered ring.
