Abstract: We have synthesized a novel, 1,4,7-triazacyclononane (TACK)- Hg2+ sandwich monomer, [{mono-N-(4-vinylbenzyl)-1,4,7- TACN}(2)Hg](OTf)(2), which was co-polymerized with the cross- linking agent divinylbenzene to form a Hg2+-ion templated polymer that was demetallated (> 96%) with 6 N HCl, and subsequently found to be highly selective to reintroduced Hg2+ ions in competition with Cd2+, Ag+, Pb2+, Cu2+, and Fe3+ ions at pH 2, the ionic radius and the thermodynamic parameter being more critical than imprinting
