项目摘要

This project, supported in the Analytical and Surface Chemistry Program, focusses on fundamental investigations of the electron transfer chemistry of organometallic compounds of interest as representative reaction intermediates in catalytic processes. During the tenure of this three-year continuing grant, Professor Geiger and his students at the University of Vermont will study the effects of structure on the electrochemical reactivity of organometallic compounds containing 17 and 19 valence electrons (17e, 19e). Using a broad suite of electrochemical and spectroscopic probes of structure and dynamics, the Vermont investigators will explore the fundamental chemistry of these systems. Additionally, they will develop new, fiber optic based infrared and near-infrared spectroelectrochemical techniques and apply them to these studies. This fundamental research addresses questions of how the structure of organometallic compounds, particularly those of cobalt and rhodium containing 17 and 19 valence electrons, affects their electron transfer properties. These questions are important to a greater understanding of the basic chemistry of these systems and the potential utility of this class of compounds in analytical sensors, photooptical devices, conducting polymers, and electrocatalysis. Additionally, this research facilitates the development of new spectroelectrochemical probes for the study of interfacial electron transfer that are expected to find broad application.

该项目在分析和表面化学计划中支持，重点介绍了感兴趣的有机金属化合物的电子转移化学作为催化过程中的代表性反应中间体。在这项为期三年的持续赠款期间，吉格教授及其学生的学生将研究结构对包含17和19价电子的有机金属化合物的电化学反应性的影响（17E，19E）。佛蒙特州研究人员使用一系列的结构和动力学探针，将探索这些系统的基本化学。此外，他们将开发新的，基于光纤的红外红外和近红外光谱电子化学技术，并将其应用于这些研究。这项基本研究探讨了有机金属化合物的结构，尤其是包含17和19价电子的钴和菱形的结构，如何影响其电子传递性能。这些问题对于对这些系统的基本化学性质以及该类别化合物在分析传感器，光学设备，导电聚合物和电催化中的潜在效用至关重要。此外，这项研究促进了新的光谱电化学探针的开发，用于研究界面电子转移的研究，这些探针有望找到广泛的应用。
