Oxidation-Reduction Mechanisms

无机化学、生物无机化学和金属有机化学项目的这一奖项支持斯坦福大学化学系Henry Taube博士对配位化学的继续基础研究。重点研究金属络合物的反应性，包括取代能力随电子结构的变化、内外球电子转移、混合价行为、伴随电子转移的键异构性以及配位配体的酸性。本课程将探讨含有不同氧化态金属的双核Os络合物，以及含有芳香族和二氢配体组合或面结合的大环配体的不寻常的Os物种。了解含金属物种的结构和电子运动的影响是发展分子水平电子学、分子开关和合成酶的重要基础。这项研究将为如何设计分子来控制电子和小原子或原子团的转移提供新的重要信息。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports continued fundamental studies of coordination chemistry by Dr. Henry Taube of the Chemistry Department, Stanford University. Emphasis will be placed on investigations of the reactivity of metal complexes, including substitution lability as a function of electronic structure, inner and outer sphere electron transfer, mixed valence behavior, linkage isomerism accompanying electron transfer, and acidity of coordinated ligands. Binuclear osmium complexes containing metals in different oxidation states will be probed, as well as unusual osmium species containing either a combination of aromatic and dihydrogen ligands, or facially-bound macrocyclic ligands. Understanding of the influence of structure and electron movement in metal-containing species is an essential underpinning for development of molecular-level electronics, molecular switches and synthetic enzymes. This research will provide new and important information on how to design molecules to control the transfer of electrons and of small atoms or groups of atoms.
