Electron Transfer Photochemistry

有机动力学项目的这笔赠款支持马里兰大学帕特里克·S·马里亚诺博士的继续工作。从这项研究中获得的知识将有助于更好地理解通过有机分子与光相互作用产生的带电物种的中介作用而发生的化学反应。此外，研究人员还将开发新的光化学反应，在合成有机化学品方面具有潜在的用途。马里亚诺博士将进行的实验旨在提供有关激发态单电子转移过程的机制过程以及结构和环境因素对这些反应效率的影响的信息。快速动力学测量将用于确定重要的溶液相离子自由基过程的速率，这些过程是一些重要的基态和激发态单电子转移过程的驱动力。探索性工作的目标将是发现新的、合成上有用的单电子转移反应和供体-受体体系的相关电化学反应。生物化学相关的光化学单电子转移反应将被用来模拟那些参与黄素蛋白氧化还原化学的反应。

This grant from the Organic Dynamics Program supports the continuing work of Dr. Patrick S. Mariano at the University of Maryland. Knowledge gained from this research will lead to a more sound understanding of chemical reactions that occur through the intermediacy of charged species generated by the interaction of organic molecules with light. In addition, the investigator will develop new photochemical reactions of potential use in the synthesis of organic chemicals. The experiments that will be carried out by Dr. Mariano are designed to provide information about the mechanistic course of excited-state single-electron-transfer processes and about the influence of structural and environmental factors on the efficiencies of these reactions. Fast kinetic measurements will be used to determine rates of important solution-phase ion radical processes, which serve as the driving force for a number of important ground-state and excited-state single-electron-transfer processes. Exploratory work will be aimed at discovery of new, synthetically useful single-electron-transfer reactions and related electrochemical reactions of donor-acceptor systems. Biochemically relevant photochemical single-electron-transfer reactions will be used to model those involved in the redox chemistry of flavoproteins.
