Studies in Organized Media

该更新项目得到了分析和表面化学项目的支持，重点关注有组织介质的基础研究，包括环糊精，聚合物环糊精和树枝状聚合物，用于分析分离，特别是毛细管电泳。 一套分子光谱技术，包括荧光，吸光度，和圆二色性，将在这些研究中使用，并将补充停流动力学方法。 在这个为期三年的项目的任期内，华纳教授和他的学生在路易斯安那州州立大学，与南方大学教授罗伯特古登合作投入-巴吞鲁日，将追求更好地了解有组织的媒体分离科学的使用的目标。 有机介质提供了第二相，分析物可以从水溶液中移动到其中。 分析物在水溶液和有机介质之间的这种分配在分离科学领域具有广泛的应用。 有机介质可以用作假固定相，并且作为赋予水溶液中原本不溶的分析物溶解度的方式。 在这个项目中，有组织的媒体，特别是环糊精和树枝状聚合物，将合成和它们的适用性分析分离的环境重要的分析物将进行评估。

This renewal project, supported in the Analytical and Surface Chemistry Program, focusses on fundamental studies of organized media, including cyclodextrins, polymeric cyclodextrins and dendrimers, for application in analytical separations with particular focus on capillary electrophoresis. A suite of molecular spectroscopic techniques, including fluorescence, absorbance, and circular dichroism, will be utilized in these studies and will be complemented by stopped-flow kinetic methods. During the tenure of this three year project, Professor Warner and his students at Louisiana State University, with collaborative input from Professor Robert Gooden of Southern University - Baton Rouge, will pursue the objective of better understanding organized media for use in separation science. Organized media provide a second phase into which analytes can move from aqueous solution. This partitioning of analytes between aqueous solution and the organized media has wide application in the field of separation science. The organized media can serve as a pseudo-stationary phase and as a way of imparting solubility to otherwise insoluble analytes in aqueous solution. In this project, organized media, particularly cyclodextrins and dendrimers, will be synthesized and their applicability in analytical separations of environmentally significant analytes will be evaluated.
