Studies of Electron Transfer Active Polymers, Polymer Solutions, and Proteins

这个项目是在分析和表面化学的一般领域和在电化学的子领域。在这项为期三年的持续资助中，Murray教授和他的学生将继续研究(1)聚合物相及其界面中电子自交换反应和电子转移交叉反应的动力学；(2)氧化还原溶质和氧化还原标记聚合物在聚合物相中的扩散动力学；(3)新型氧化还原聚合物和混合价聚合物相的设计与合成；(4)选定氧化还原蛋白的电子转移化学。聚合物相实验涉及聚合物熔体和玻璃，而不是更传统的单体流体溶剂。这项研究将导致设计新的基于电化学的测量策略，以获得对理解电子传递和质量传递动力学的基本原理有用的数据。此外，它还将导致新的氧化还原聚合物电解质类别和对其物理化学的新见解，从而使它们能够有效地应用于新型电化学传感器技术。

This project is in the general area of analytical and surface chemistry and in the subfield of electrochemistry. During the tenure of this three-year continuing grant, Professor Murray and his students will pursue studies in (1) the dynamics of electron self-exchange reactions and electron transfer cross-reactions in polymeric phases and at their interfaces; (2) the diffusion dynamics of redox solutes and of redox-labeled polymers within polymeric phases; (3) the design and synthesis of new redox polymers and mixed valent polymer phases; and (4) the electron transfer chemistry of selected redox proteins. The polymer phase experiments involve polymer melts and glasses rather than the more conventional monomeric fluid solvents. %%% This research will lead to the design of new electrochemically based measurement tactics for obtaining data useful in understanding the fundamental principles involved in electron transfer and mass transport dynamics. Also, it should lead to new classes of redox polymer electrolytes and new insights into their physical chemistry that will enable their effective utilization in novel electrochemical sensor technology.
