Studies into the coordination environment of cobalt on a tethered polyamine

Edward Rosenberg and Jesse James Allen. University of Montana, Missoula, MT

The oxidation of divalent cobalt in the presence of coordinating nitrogen compounds on a rigid surface is a rather interesting phenomenon. The trivalent cobalt state is stabilized to the point of being preferred in the presence of coordinating nitrogen ligands, but such an occurrence is commonly seen in the solution state with small ligands, rather than on a polymer with multiple anchor points to a rigid surface. Additionally, the relative stability of such a complex, as well as its 3+ charge gives it potential for further use as an anion exchange composite.
