Structural Dependences of Long Distance Electron Transfer Reactions

这个奖项是在有机动力学项目中颁发给布朗大学的Matthew zimt博士的。zimt博士的工作目标是推进对电子如何在空间中转移的基本理解。这一过程对许多化学和生化反应以及有机微电子学具有重要意义。对称、取向和键连通性在分子内转移调制速率中的作用将被解决。要研究的主要系统包括一组新的供体-间隔体-受体分子，这些分子在供体和受体之间建立了明确的几何关系。这些研究结果对分子级电子元件的设计具有一定的指导意义。在传递参数被强烈调制的系统中，构象迁移率的动态结果将被研究。要研究的系统将包括所有三种类型的电子转移：电荷分离，电荷重组和电荷移动。研究了周围介质的结构对电子转移反应的速率和范围的影响。

This award is made in the Organic Dynamics Program to Dr. Matthew Zimmt at Brown University. The goal of Dr. Zimmt's work is to advance the fundamental understanding of how electrons are transferred across space. This process is of great significance to a number of chemical and biochemical reactions as well as organic microelectronics. The role of symmetry, orientation and bond connectivity in modulating rates of intramolecular transfer will be addressed. The primary systems to be studied comprise a novel set of donor-spacer-acceptor molecules which enforce an unambiguous geometric relationship between donor and acceptor. The results of these studies are relevant for the design of molecular scale electronic components. The dynamic consequence of conformational mobility in systems where transfer parameters are strongly modulated will be investigated. The systems to be investigated will include all three types of electron transfers: charge separation, charge recombination and charge shift. The effect of the structure of the surrounding medium on the rate and range of electron transfer reactions will also be investigated.
