Abstract: A Zn2+ templated polymer, containing a sandwich arrangement of the well known 1,4,7-triazacyclononane (TACN) ligand, was found to be highly selective toward reintroduced Cu2+ in the presence of Fe3+, Co2+, Ni2+, Zn2+, and Mn2+, after the removal of the Zn2+ ion template with 6 N HC1; while a similar Hg2+ templated TACN polymer was found to be highly selective for Hg2+ in the presence of Cd2+, Pb2+, Ag+, Cu2+, and Fe3+. The following parameters were addressed: structures of the monomers of the N-(4-vinylbenzyl)TACN-Zn2+/Hg2+ complexes; polymerization parameters; structure of the polymer TACN-template metal ion complex; and selectivity to reintroduced metal ions as a function of the thermodynamic stability and the metal ion templating parameters for the polymer TACN-metal ion complexes that are formed
