项目摘要

Professor Royce Murray and his colleagues at the University of North Carolina-Chapel Hill are examining the chemistry and electrochemistry of metal nanoparticles containing a few hundred atoms and coated with a monolayer of thiolate ligands. With the support of the Analytical and Surface Chemistry Program, this project focusses on the synthesis of these monolayer protected clusters, and their characterization using various chemical and electrochemical means. In addition, this group studies electron transfer dynamics in mixed valent molecular molten salts. The goal of the work is to understand the basic properties of nanoparticulate matter and electron transfer dynamics in these systems and in the semi-solid molecular molten salts. The synthesis and characterization of a novel class of molecular nanoparticles is the goal of this research project at the University of North Carolina in Chapel Hill. Using thiolate ligands to protect metal particles of a few hundred atoms, materials that can be manipulated and characterized using electrochemical methods are being developed. This research project also includes the study of electron transfer processes in mixed valent molecular molten salts. Both aspects of the research are directed to a basic understanding of charge transfer in nanomaterials and solids.

北卡罗来纳大学教堂山分校的罗伊斯·默里教授和他的同事们正在研究金属纳米颗粒的化学和电化学，这些纳米颗粒包含数百个原子，并覆盖了一层硫酸盐配体。在分析和表面化学计划的支持下，本项目专注于这些单层保护簇合物的合成，并使用各种化学和电化学手段对其进行表征。此外，该小组还研究了混合价分子熔盐中的电子转移动力学。这项工作的目标是了解纳米颗粒物质的基本性质和在这些系统中以及在半固态分子熔盐中的电子转移动力学。北卡罗来纳大学教堂山分校的这项研究项目的目标是合成和表征一类新型的分子纳米粒子。利用硫酸盐配体保护几百个原子的金属颗粒，可以用电化学方法操纵和表征的材料正在开发中。本研究项目还包括研究混合价分子熔盐中的电子转移过程。这两个方面的研究都旨在对纳米材料和固体中的电荷转移有一个基本的了解。
