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拨款支持了密歇根大学Mark Meyerhoff教授的研究，重点是开发基于卟啉的固定相，用于分离富勒烯家族化合物的成员。通过改变卟啉环内金属离子的身份和电化学控制金属中心的氧化态，可以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，富勒烯的发现发展了一种新型的化学。这些化合物的骨架仅以碳原子为基础，并且具有对称结构，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，具有很大的前景。这项由化学部门支持的研究将使这些新材料得到更详细的表征。这些研究将有可能使这些独特物种的大量分离成为可能，这对于基于这些化合物开发新材料至关重要。

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.
