Supramolecular Chemistry of Selective Anion Recognition for Anions of Environmental Relevance
This project involves the design and synthesis of receptors for anions of environmental importance, including emphasis on high level and low activity waste. Polyammonium macrocycles as receptors and nitrate as target anion were the focus of the first phase of this project. A second phase involved the synthesis of lipophilic amide based receptors in order to increase the potential for obtaining workable receptors for both separations and sensing applications on site. In the renewal of this project, anions have been extended especially to include selective recognition and binding of sulfate. A three tier approach was employed: I. Design, synthesis, and physical and structural characterization of receptors; II. Examination of the technique known as ITIES, Interface Between Two Immiscible Electrolyte Solutions, as an analytical probe for anion analysis; and III. Separations studies using lipophilic amide receptors for anion binding done at the Oak Ridge National Laboratory by Bruce Moyer. The result of this program will impact a variety of needs of the Environmental Science Management Program in both sensing and separations areas.
