溶剂化在界面电化学中的作用是本研究项目的重点，该项目得到了分析和表面化学计划的支持。离子转移反应，光谱学和电化学法，将用于研究溶剂化的机理。用自组装单分子膜修饰的单晶金电极是这项工作的基础。水在这些界面上的作用将通过导纳测量和简单的电子转移测试反应来探索。我们将研究快速电子转移过程中的溶剂化，并发展这些体系的溶剂化理论。这项研究产生的信息将有助于加深对生物膜系统中电荷转移和控制的理解。有机单分子膜修饰金电极上电荷转移的实验和理论研究是本课题研究的重点。了解这些模型膜中电子传递的机理和动力学将有助于理解溶剂化作用在这些生物模型体系中的作用。

The role of solvation in interfacial electrochemistry is the focus of this research project, supported by the Analytical and Surface Chemistry Program. Ion transfer reactions, probed spectroscopically and electrochemically, will be used to study the mechanism of solvation. Single crystal gold electrodes modified with self-assembled monolayers form the basis of the work. The role of water at these interfaces will be probed using admittance measurements and simple electron transfer test reactions. Solvation in very fast electron transfer processes will be examined, and the theory of solvation for these systems will be developed. The information generated by this study will be useful in developing an understanding of charge transfer and control in biological membrane systems. An experimental and theoretical study of charge transfer at organic monolayer modified gold electrodes is the focus of this research project. Understanding the mechanism and kinetics of electron transport across these model membranes will be useful for understanding the role of solvation in these biological model systems.
