Dr. Thomas B. Rauchfuss of the University of Illinois at Urbana-Champaign will design and synthesize a variety of molecular and solid-state metal sulfide compounds. The four specific areas of study include metal-centered reactivity in M4S3 clusters and osmium- and iron-sulfides, examining structure/reactivity trends in M3S4 clusters, development of new routes to dimers and polymers containing metal clusters, and manipulating the stability and stoichiometry of newly discoverd C60-S-Fe adducts. A basic premise of the cluster work is that reactive entities are best prepared by subtle means compatible with the preservation of highly reactive sites, and patterns delineated in this study are expected to provide a context for correlating a significant body of molecular and solid state chemistry. Dr. Rauchfuss will also explore new hybrid bio-organometallic materials and new carbon sulfides derived from C60 which bridge the interface between inorganic and organometallic sulfide chemistry. The overall goal of this research is a molecular-level understanding of the synthesis, reactivity, and structure of metal sulfides. The information obtained from this work provides an underpinning for new catalytic technologies, new materials, and most importantly, the discovery of unexpected new chemical phenomena. The work is motivated by the broad relevance of metal sulfide systems and the chemsitry of elemental sulfur to such materials. Furthermore, the work is expected to lead to the discovery of new chemical phenomena related to materials used to clean fossil fuels, to transform atmospheric nitrogen into life-giving ammonia, and to capture and transfer energy from the sun.

伊利诺伊大学香槟分校的Thomas B.Ruchfuss博士将设计和合成各种分子和固态金属硫化物化合物。这四个具体的研究领域包括：M4S3团簇和奥硫化物和铁硫化物中的金属中心反应性，检测M3S4团簇中的结构/反应趋势，开发二聚体和含有金属团簇的聚合物的新途径，以及操纵新发现的C60-S-Fe加合物的稳定性和化学计量比。簇工作的一个基本前提是，活性实体的最佳制备方法与高活性位点的保存相兼容，本研究中描述的模式有望为关联重要的分子和固态化学提供背景。拉什弗斯博士还将探索新的生物-有机金属杂化材料和从C60衍生的新的碳硫化物，它们是无机和有机金属硫化物化学之间的桥梁。这项研究的总体目标是从分子水平上了解金属硫化物的合成、反应活性和结构。从这项工作中获得的信息为新催化技术、新材料以及最重要的是发现意想不到的新化学现象提供了基础。这项工作的动机是金属硫化物系统和元素硫的化学与此类材料的广泛相关性。此外，这项工作有望发现与清洁化石燃料、将大气氮转化为赋予生命的氨以及捕获和转移来自太阳的能量所用材料有关的新化学现象。
