EAGER: Subsulfide and Subselenide Chemistry

CHE分部化学合成(SYN)项目的这一奖项支持威斯康星大学约翰·F·贝里教授的工作？麦迪逊开展硫和硒与过渡金属结合的氧化还原性质的基础研究。这些研究将检验这样一种假设，即硫的一种新的氧化态，亚硫化物，可以通过与过渡金属的配位来稳定。这项研究涉及使用各种物理方法检查以前报道的硫/过渡金属化合物以及新设计的化合物的电子结构。研究配位硫物种的电化学反应活性，以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-硫键的性质是许多重要的生物学问题和新技术的关键。亚硫化物化学的发展可以对理解蛋白质中二硫键的形成产生长期的影响，并可能导致新的技术，如新的催化工艺和用于光伏器件的染料。

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.
