Dynamics and Interactions in Ionic Liquids

化学部的实验物理化学计划支持新泽西州立大学罗格斯大学化学与化学生物学系的Edward Castner教授的研究。 卡斯特纳和他的研究小组将研究新类型离子液体的物理和化学性质。 时间分辨光谱和核磁共振光谱将用于研究离子液体中的动力学，相互作用和运输作为温度的函数。 该研究将包括详细评估烷基侧链中硅取代对这些材料性能的影响，以及离子液体中分子间相互作用与等电子中性同系物的比较。 具有不同浓度的水的离子液体的NMR扩散研究将用于模拟燃料电池中的离子液体相关的传输。 这项工作的总体目标是仔细研究选定的离子液体和足够详细的模型系统，以更好地预测其性质。 该研究将有助于更好地了解离子液体的液体性质，特别是它们的粘度和电导率。 离子液体是一类重要的新型化学溶剂，由具有许多特殊性质的熔融盐组成。 这些液体的独特电特性应导致它们在改进的电池、燃料电池和太阳能光电电池中的使用。 卡斯特纳小组将与各种各样的研究人员合作，包括布鲁克海文国家实验室、威廉帕特森大学和纽约城市大学（亨特学院和布鲁克林学院）的学生、博士后研究员、教师和科研人员。 该项目将培养本科生，研究生和博士后研究人员在实验和理论物理化学的现代技术。

The Experimental Physical Chemistry program of the Division of Chemistry supports the research of Professor Edward Castner of the Department of Chemistry and Chemical Biology at Rutgers, The State University of New Jersey. Castner and his research group will study the physical and chemical properties of new classes of ionic liquids. Time-resolved optical spectroscopy and nuclear magnetic resonance spectroscopy will be used to study the dynamics, interactions, and transport in ionic liquids as a function of temperature. The research will include the detailed evaluation of the impact of silicon substitutions in alkyl side chains on the properties of these materials and the comparison of intermolecular interactions in ionic liquids with those of isoelectronic, neutral homologs. NMR diffusion studies of ionic liquids with varying concentrations of water will be used to model transport relevant to ionic liquids in fuel cells. The overall goal of the work is to study carefully selected ionic liquids and model systems in sufficient detail to lead to better a priori predictions of their properties. The research should provide a better understanding of the liquid properties of ionic liquids, especially their viscosities and conductivities. Ionic liquids are an important new class of chemical solvents comprised of molten salts that have many special properties. The unique electrical characteristics of these liquids should lead to their use in improved batteries, fuel cells and solar photocells. The Castner group will collaborate with a diverse range of researchers, including students, postdoctoral fellows, faculty, and scientific staff at Brookhaven National Laboratory, William Paterson University, and the City University of New York (Hunter College and Brooklyn College). The project will train undergraduates, graduate students, and post-doctoral researchers in modern techniques in experimental and theoretical physical chemistry.
