Center for Photoinduced Charge Transfer

这项由罗切斯特大学与伊士曼柯达公司和施乐公司联合提出的提案，要求为建立光致电荷转移科学技术中心提供资金。该中心的主任将是David G. Whitten教授。本研究的目标是在分子水平上理解光诱导电荷转移过程的四个主要事件（即活化过程；初始电荷转移；电荷分离、传输和捕获；带电物质的化学反应）。因此，研究将集中在电子转移过程本身的基础上。该中心将研究不同介质（包括固体、有组织和非晶态介质）、半导体粒子、跨界面和流体介质中的光激发和场辅助电荷分离和输运。这些研究自然会导致光生物过程的光谱，其中电子转移起着关键作用。平行的努力将指向电子转移过程的应用。这类研究的一个例子是通过单电子转移来探索化学键的激活。这三个地点的研究专业知识的广度最适合拟议的研究活动，包括固态物理、材料科学、电化学和制备化学、新激光技术以及胶体和表面科学。

This proposal from the University of Rochester, in association with the Eastman Kodak Company and the Xerox Corporation requests funds to establish a Science and Technology Center for Photoinduced Charge Transfer. The Director of the Center will be Professor David G. Whitten. The goal of the research is to achieve a molecular level understanding of the four major events of photoinduced charge transfer processes (i.e., activation processes; initial charge transfer; charge separation, transport and trapping; chemical reactions of charged species). Thus, the research will focus on the fundamentals of electron transfer processes themselves. The Center will involve studies of photoexcitation and field-assisted charge separation and transport in diverse media (including solids, organized, and amorphous media), in semiconductor particles, across interfaces, and in fluid media. These studies will naturally lead into the spectrum of photobiological processes, where electron transfer plays a key role. Parallel efforts will be directed towards applications of electron transfer processes. One example of this type of study will be the exploration of chemical bond activation by single electron transfer. The breadth of the research expertise at the three sites is most appropriate for the proposed research activities, ranging from solid state physics, materials science, to electrochemistry and preparative chemistry, new laser technology, and colloid and surface science.
