Center for Photoinduced Charge Transfer

罗切斯特大学与伊士曼柯达公司和施乐公司联合提出的这项提案要求提供资金，以建立一个光致电荷转移科学技术中心。中心主任将由David G.Whitten教授担任。这项研究的目的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(即激活过程；初始电荷转移；电荷分离、传输和捕获；带电物种的化学反应)。因此，这项研究将集中在电子转移过程本身的基本原理上。该中心将研究不同介质(包括固体、有序和非晶态介质)、半导体颗粒、跨界面和流体介质中的光激发和场辅助电荷分离和传输。这些研究将自然而然地引入光生物过程的光谱，其中电子转移起着关键作用。同时，还将针对电子转移过程的应用开展工作。这种类型的研究的一个例子是探索通过单电子转移来激活化学键。这三个地点的研究专门知识的广度最适合拟议的研究活动，范围从固体物理、材料科学到电化学和制备化学、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.
