RUI: Complexation Studies of Heavy Metal Ions by Crown Polythioethers and Related Macrocyclic Ligands

田纳西大学查塔努加化学系的Gregory Grant得到无机、生物无机和有机化学项目的支持，研究冠状聚硫醚和混合供体配体对重金属的络合作用。本研究将研究环的大小和给体原子（硫、磷、氮、氧）对金属配合物的稳定性和结构的影响。多核核磁共振波谱（包括199-Hg，113-Cd和207-Pb NMR）可以提供这些配合物在溶液中的详细结构信息，在环境修复、催化、药物化学、分离和电化学传感器等方面具有潜在的应用价值。该研究项目将提供对这些配合物中金属-配体相互作用的基本理解。该奖项是在“本科院校研究计划”下颁发的，强调本科院校的教学和研究的一体化。本科研究人员将学习这些化合物的合成和表征的重要技能。

Gregory Grant, Department of Chemistry, University of Tennessee Chattanooga, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for research on the complexation of heavy metals by crown polythioethers and mixed donor ligands. The research will study the influence of ring size and donor atom (sulfur, phosphorus, nitrogen, oxgen) on the stability and structure of metal complexes. Multinuclear nuclear magnetic resonance spectroscopy, including 199-Hg, 113-Cd and 207-Pb NMR will provide detailed structural information about these complexes in solution.Complexation chemistry has potential impacts in environmental remediation, catalysis, medicinal chemistry, separations and electrochemical sensors. This research project will provide fundamental understanding of the metal-ligand interactions in these complexes. This award is made under the "Research in Undergraduate Institutions Program" and emphasizes the intergration of teaching and research at undergraduate institutions. Undergraduate researchers will learn important skills in synthesis and characterization of these chemical compounds.
