Saccharide-mediated Electron Transfer

这项研究在马里兰大学巴尔的摩分校Lisa Kelly教授的实验室进行，由研究计划资助下的无机、生物无机和有机金属化学项目提供支持。该研究涉及使用钌配合物拴住碳水化合物，以探索碳水化合物作为电子转移（ET）介质。与联吡啶螯合基团结合的硼酸将用于将金属中心与1,2和1,3二醇官能团结合。热力学驱动力和中间糖空间的长度会发生变化。如果还原性解离与电荷重组竞争，受体的释放可能会引入新的策略来提高电荷分离的效率。一类涉及环糊精腔内外供体/受体对ET的配合物将被研究。这项研究将扩展我们对通过重要生物材料进行电子传递的理解。

This research in the laboratory of Professor Lisa Kelly at the University of Maryland Baltimore County Campus is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program under a Research Planning Grant. The research involves the use of ruthenium complexes tethered to carbohydrates in order to explore carbohydrates as electron-transfer (ET) mediators. Boronic acid tied to bipyridine chelating groups will be used to bind the metal centers to 1,2 and 1,3 diol functional groups. Thermodynamic driving force and the length of the intervening saccharide space will be varied. If reductive dissociation is competitive with charge recombination, the release of the acceptor may introduce new strategies for increasing the efficiency of charge separation. A class of complexes involving the ET the donor/acceptor pair divided between the inside and outside of cyclodextrin cavities will be investigated. This research will extend our understanding of electron transfer through biologically important materials.
