Grant for Exploratory Research: Immobilized Porphyrins as Versatile Stationary Phases in Liquid Chromatography

这项为期一年的分析和表面化学项目探索性研究小额助学金支持密歇根大学Mark Meyerhoff教授的研究，重点是开发基于卟啉的固定相，用于分离富勒烯化合物家族的成员。通过改变位于卟啉环内的金属离子的同一性，以及通过电化学控制金属中心的氧化状态，将改变卟啉相的分离特性。其他潜在的应用包括多芳烃分析和多肽分离。近年来，随着富勒烯的发现，一种新型的化学已经发展起来。这些化合物的框架只基于碳原子，并且具有对称的结构，例如，足球形状的C60。这些化合物作为具有独特性能的新材料，如润滑剂，显示出巨大的前景。这项由化学司支持的研究将使这些新材料得到更详细的表征。这些研究可能会使大量这些独特物种的分离成为可能，这对基于这些化合物的新材料的开发至关重要。

This one year Small Grant for Exploratory Research in the Analytical and Surface Chemistry Program supports the research of Professor Mark Meyerhoff at the University of Michigan, and is focused on the development of porphyrin-based stationary phases for the separation of members of the fullerene family of compounds. The separation characteristics of the porphyrin phases will be altered by changing the identity of the metal ion located within the porphyrin ring, and by electrochemically controlling the oxidation state of the metal center. Other potential applications include polyaromatic hydrocarbon analyses and peptide separations. In recent years, a new type of chemistry has been developed based on the discovery of the fullerenes. These are compounds with a framework based only on carbon atoms and which have symmetrical structures, for example, the soccer ball-shaped C60. These compounds show a great deal of promise as new materials with unique properties, e.g., lubricants. This research, supported by the Chemistry Division, will allow these new materials to be characterized in much more detail. These studies will potentially allow for the isolation of large quantities of these unique species, which is critical for the development of new materials based on these compounds.
