Organic Chemistry of Free Atoms, Particles, and Their Mimics

无机、生物无机和有机金属化学项目的基本主题是对高活性物质的化学解释及其衍生产物的研究。将采用金属蒸汽和常规合成方法制备早期过渡金属的氟碳配合物。在低温溶剂中，金属和分子团簇的捕获将通过溶剂化和/或配体注入来完成。利用结构敏感反应化学和光谱探针，特别是EXAFS、Mossbauer和XPS技术，对双金属溶剂化金属原子分散（SMAD）催化剂进行进一步的研究。为了充分发挥高活性CS的潜力，将尝试合成在相对较高温度下进化CS的前体。本项目正在研究的几种物质具有工业应用潜力。在这方面特别令人感兴趣的是精心控制尺寸的金属原子簇和高活性的SMAD催化剂。

The underlying theme of this project in the Inorganic, Bioinorganic and Organometallic Chemistry Program is the chemical elucidation of highly reactive species and the study of products derived therefrom. Metal vapor and conventional synthetic methodology will be employed to prepare fluorocarbon complexes of early transition metals. Trapping of metallic and molecular clusters will be accomplished by solvation and/or ligand injection during cluster growth in low temperature solvents. Further elucidation of bimetallic solvated metal atom dispersed (SMAD) catalysts will be carried out using structure sensitive reaction chemistry coupled with spectroscopic probes, especially EXAFS, Mossbauer and XPS techniques. In order to develop the highly reactive synthon CS to its full potential, attempts will be made to synthesize precursors which evolve CS at relatively elevated temperatures. Several of the substances under study in this project have potential for industrial applications. Of particular interest in this connection are the metal atom clusters of carefully-controlled size and the highly reactive SMAD catalysts.
