This award in the Chemical Synthesis (SYN) program within the CHE Division supports work by Professor John F. Berry at the University of Wisconsin ? Madison to carry out fundamental studies of the redox properties of sulfur and selenium bound to transition metals. These studies will test the hypothesis that a new oxidation state of sulfur, subsulfide, can be stabilized by coordination to transition metals. This investigation involves examination of the electronic structure of previously reported sulfur/transition metal compounds, as well as newly designed compounds, using a variety of physical methods. Electrochemical and chemical reactivity of coordinated sulfur species will be investigated so that the electronic and chemical properties of the subsulfide ion may be elucidated.The oxidation and reduction chemistry of sulfur and the nature of sulfur-sulfur bonding are critical to many important biological problems and new technologies. The development of subsulfide chemistry can have a long-term impact on the understanding of disulfide bond formation in proteins, and can potentially lead to new technologies such as new catalytic processes and dyes for photovoltaic devices.

CHE 部门化学合成 (SYN) 项目的该奖项支持威斯康星大学 John F. Berry 教授的工作？麦迪逊对与过渡金属结合的硫和硒的氧化还原性质进行基础研究。 这些研究将检验硫的新氧化态（低硫化物）可以通过与过渡金属配位来稳定的假设。 这项研究涉及使用各种物理方法检查先前报道的硫/过渡金属化合物以及新设计的化合物的电子结构。 将研究配位硫物质的电化学和化学反应性，以便阐明亚硫离子的电子和化学性质。硫的氧化和还原化学以及硫-硫键的性质对于许多重要的生物学问题和新技术至关重要。 亚硫化物化学的发展可以对蛋白质中二硫键形成的理解产生长期影响，并有可能带来新技术，例如用于光伏器件的新催化过程和染料。
