Organic Chemistry of Free Atoms, Particles, and Their Mimics

无机化学、生物无机化学和金属有机化学项目的基本主题是高活性物种的化学阐明和由此衍生的产物的研究。将采用金属蒸气和传统的合成方法来制备早期过渡金属的氟碳配合物。金属和分子团簇的捕获将通过溶剂化和/或配体注入在低温溶剂中生长团簇来完成。利用结构敏感反应化学结合光谱探针，特别是EXAFS、穆斯堡尔谱和XPS技术对双金属溶剂化金属原子分散(SMAD)催化剂进行了进一步的研究。为了开发高活性的合成子CS以充分发挥其潜力，将尝试合成在相对较高的温度下产生CS的前体。该项目中正在研究的几种物质具有工业应用的潜力。在这方面特别令人感兴趣的是尺寸精心控制的金属原子团簇和高活性的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.
