“…Imprinted polymers designed to bind to specific macrocyclic complexes have been investigated for potential applications in the separation or extraction of metal ions. 111 There is considerable interest in the use of macrocyclic compounds with Lewis acidic or redox active centres in the hydrolytic cleavage of biologically relevant molecules such ATP, DNA and RNA. The remainder of this section provides details of a number of examples from 2005.…”

“…Allyl pendant arms have a terminal alkene functional group for this purpose within our experimental design. The allyl-pendant-armed ligands and complexes can copolymerize following the work of Zuo for ethylene glycol di-methacrylate (EGDMA) polymerization [ 44 ]. This copolymerization has been quite successful in our hands and will be the subject of future manuscripts.…”

Twenty novel Mn, Fe, and Cu complexes of ethylene cross-bridged tetraazamacrocycles with potentially copolymerizable allyl and benzyl pendant arms were synthesized and characterized. Multiple X-ray crystal structures demonstrate the cis-folded pseudo-octahedral geometry forced by the rigidifying ethylene cross-bridge and show that two cis coordination cites are available for interaction with substrate and oxidant. The Cu complexes were used to determine kinetic stability under harsh acidic and high-temperature conditions, which revealed that the cyclam-based ligands provide superior stabilization with half-lives of many minutes or even hours in 5 M HCl at 50–90 °C. Cyclic voltammetry studies of the Fe and Mn complexes reveal reversible redox processes indicating stabilization of Fe2+/Fe3+ and Mn2+/Mn3+/Mn4+ oxidation states, indicating the likelihood of catalytic oxidation for these complexes. Finally, dye-bleaching experiments with methylene blue, methyl orange, and rhodamine B demonstrate efficient catalytic decolorization and allow selection of the most successful monomeric catalysts for copolymerization to produce future heterogeneous water purification materials.

“…6,7 Current technologies for ClO 4 À removal from drinking water and groundwater include adsorption, 8,9 ion exchange, 10,11 chemical reduction [12][13][14] bioremediation, 14,15 etc. An ion imprinted polymer (IIP) [16][17][18] is able to recognize ions whilst keeping the unique virtues of molecular imprinting polymers (MIP), i.e., structure predictability, recognition speci-city and application universality. Owing to special coordination or electrostatic interactions, IIPs are generally compatible with aqueous media and have advantages over most MIPs.…”
