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

田纳西大学查塔努加大学化学系Gregory Grant由无机、生物无机和有机金属化学计划支持，研究冠状多硫醚和混合供体配体对重金属的络合作用。本研究将研究环大小和施主原子(硫、磷、氮、氧)对金属络合物稳定性和结构的影响。多核核磁共振波谱，包括199-汞，113-镉和207-铅核磁共振将提供这些化合物在溶液中的详细结构信息。络合化学在环境修复、催化、药物化学、分离和电化学传感器方面具有潜在的影响。这一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。该奖项是根据“本科院校研究计划”颁发的，强调本科院校教学和研究的一体化。本科生研究人员将学习合成和表征这些化合物的重要技能。

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.
