该项目在分析和表面化学计划的支持下，重点关注感兴趣的有机金属化合物作为催化过程中代表性反应中间体的电子转移化学的基础研究。 在为期三年的持续资助期间，佛蒙特大学的盖革教授和他的学生将研究结构对含有17和19价电子的有机金属化合物的电化学反应性的影响。 使用一套广泛的电化学和光谱探针的结构和动力学，佛蒙特州的研究人员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和近红外光谱电化学技术，并将其应用于这些研究。 这项基础研究解决了有机金属化合物的结构，特别是含有17和19价电子的钴和铑的结构如何影响其电子转移性质的问题。 这些问题对于更好地理解这些系统的基本化学以及这类化合物在分析传感器、光电器件、导电聚合物和电催化中的潜在效用是重要的。 此外，这项研究有利于开发新的光谱电化学探针的界面电子转移的研究，有望找到广泛的应用。

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.
