U.S.-Argentina Cooperative Research: Intramolecular Electron Transfer in the Inverted Region

小行星9503885 这个美国-巴西合作科学计划奖支持研究生从查佩尔山的北卡罗来纳州大学的托马斯迈耶博士实验室到N. Katz，Universidad Nacional de图库曼，图库曼，阿根廷. 支持三次为期两个月的访问。 反过来，阿根廷方面将支持卡茨博士实验室的科学家对北卡罗来纳州大学进行为期两个月的访问。 一些消耗性研究用品和出版费用也在该奖项下得到支持。 研究领域是一个重要的领域，因为它涉及到光化学/物理学的基本理解和更实际的领域，如太阳能转换。本工作将涉及一系列含Re（I，II）和Mo（I，0）的混合价二聚体分子内电子转移的研究。 这些配合物将被设计为使得光诱导Re到Mo电子转移的氧化还原电位可以通过配体修饰而变化。 在所有的情况下，驱动力将大于重组能量，使该过程发生在马库斯的“倒置区域”。 这些研究将补充和扩展迈耶的研究，金属配体的电荷转移在倒置的区域，这是集中在单金属配合物。 在业务上，北卡罗来纳州和阿根廷集团的优势将得到有效利用。 虽然化合物的设计是一项共同的责任，但准备工作将在图库曼进行，那里的实验室和工作人员拥有许多合成专业知识。 然后，这些复合物将被运送到诺普斯卡罗莱纳，在那里将使用迈耶高度专业化的激光设施进行光化学实验。 为了产生一个有效结合两个研究小组的个人才能的连贯的研究团队，研究计划包含了美国和阿根廷实验室之间工作人员交流的详细时间表。 ***

9503885 Meyer This U.S.-Brazil Cooperative Science Program award supports travel expenses for graduate students from the laboratory of Dr. Thomas Meyer, Univ. of North Carolina, Chapel Hill to the laboratory of Dr. N. Katz, Universidad Nacional de Tucuman, Tucuman, Argentina. Three visits of two month duration are supported. The Argentine side, in turn, will support three two month long visits by scientists from Dr. Katz' lab to the Univ. of North Carolina. Some expendable research supplies and publication costs are also supported under this award. The area of investigation is an important one, both as it relates to the basic understanding of photochemistry/physics and to more practical areas, such as solar energy conversion. The work will involve investigations in intramolecular electron transfer in a series of mixed- valence dimers containing Re(I, II) and Mo(I,0). These complexes will be designed such that the redox potential of photoinduced Re to Mo electron transfer can be varied by ligand modifications. In all cases the driving force will be greater than the reorganizational energy, so that the process occurs in the Marcus "inverted region". These studies will complement and extend Meyer's research on metal- ligand charge transfer in the inverted region , which has centered on monometallic complexes. Operationally, the strengths of the North Carolina and the Argentine groups will be efficiently utilized. While the design of the compounds is a joint responsibility, preparative work will be carried out in Tucuman, where the laboratory and personnel have much synthetic expertise. The complexes will then be transported to Nopth Carolina, where the photochemical experiments will be carried out, using Meyer's highly specialized laser facilities. In order to produce a coherent research team that effectively combines the individual talents of the two research groups, the research plan contains a detailed schedule for the interchange of workers b etween the U.S. and the Argentine laboratories. ***
