Multielectron Photochemistry of Small Molecules

马萨诸塞州理工学院的丹尼尔·诺塞拉教授因其研究探索如何利用光来驱动小分子的多电子转化而获得化学系的支持，重点是与能量相关的底物。 新的见解设计的多电子试剂，电子结构倾向于多电子反应性，和多电子转移过程的机制将出现从这项研究。 二电子混合价化学的发展为发展小分子活化和能量转换的多电子光过程提供了类似的前景，满足下一个世纪全球能源需求需要更好地理解制定新的碳中性能量转换方案的关键基础科学问题。 为了理解能量后果的小分子的活化和使用的化学，包括二氧化碳，氮气和甲烷，除了氢气，水和氧气之外，新的多电子无机氧化还原反应将被研究，目的是理解金属络合物在电子激发态的反应性，而不是传统的单电子转移。 合成与光化学和光谱学的结合将为本科生，研究生和博士后提供前沿无机化学课程的独特培训体验。

Professor Daniel Nocera of the Massachusetts Institute of Technology is supported by the Division of Chemistry for his research exploring how light can be used to drive multielectron transformations of small molecules with emphasis on energy related substrates. New insights into the design of multielectron reagents, of electronic structure predisposed to multielectron reactivity, and of the mechanism of multielectron transfer processes will emerge from this research. The development of two-electron mixed-valence chemistry holds similar promise for developing multielectron photoprocesses of small molecule activation and energy conversion.Meeting global energy needs over the next century requires greater understanding of key fundamental science issues for the elaboration of new carbon-neutral energy conversion schemes. To understand the chemistry of the activation and use of small molecules of energy consequence, including carbon dioxide, nitrogen and methane, in addition to hydrogen, water and oxygen, new multielectron inorganic redox reactions will be investigated with the aim of understanding of the reactivity of metal complexes in electronic excited states beyond conventional one-electron transfer. The combination of synthesis with photochemistry and spectroscopy will give undergraduates, graduate students and postdocs a unique training experience in a forefront inorganic chemistry program.
