Structural Dependences of Long Distance Electron Transfer Reactions

该奖项由布朗大学的马修·齐姆特博士在有机动力学项目中颁发。齐姆特博士的工作目标是推进对电子如何跨越空间转移的基本理解。这一过程对许多化学反应和生化反应以及有机微电子学都具有重要意义。对称性、取向和键连接性在调节分子内转移速率中的作用将被讨论。要研究的主要体系包括一组新的给体-间隔基-受体分子，它们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尺度电子元件的设计具有一定的指导意义。在转移参数被强烈调制的系统中，构象迁移率的动力学结果将被研究。要研究的系统将包括所有三种类型的电子转移：电荷分离、电荷复合和电荷移位。还将研究周围介质的结构对电子转移反应的速度和范围的影响。

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.
