This proposal requests funds to permit Dr. Patrick S. Mariano, Department of Chemistry, University of Maryland, to pursue with Dr. Ung Chan Yoon, Department of Chemistry, Pusan National University, for a period of 24 months, a program of cooperative research on electron transfer-induced photochemical reactions of organic systems. Specifically, sequential electron transfer-electrofugal group elimination sequences, promoted by excitation of reacting substrates or electron transfer photosensitizers, will be employed as general methods for generation of heteroatom substituted carbon radicals. The mechanistic details and synthetic applications of these processes will be probed. This project is a continuation of the cooperative research of the two investigators supported under NSF Grant No. INT-8717920, and adds an international cooperative dimension to Dr. Mariano's current research under NSF Grant No. CHE-8917725. Their previous collaborative research has been highly successful and has resulted in several joint publications in refereed journals. This successful collaboration has generated ideas which serve as the basis for continuing joint research. The studies planned for the period of continued collaboration should provide knowledge about various aspects of the new area of electron transfer photochemistry (photoelectrochemistry) and about new and potentially efficient methods for construction of complex molecular structures. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.

本提案要求资助马里兰大学化学系Patrick S. Mariano博士与釜山国立大学化学系Ung Chan Yoon博士进行为期24个月的有机系统电子转移诱导光化学反应的合作研究项目。具体来说，通过激发反应底物或电子转移光敏剂促进的顺序电子转移-电性基消除序列将被用作生成杂原子取代碳自由基的一般方法。本文将探讨这些过程的机理和综合应用。本项目是两位研究者在美国国家科学基金（NSF）资助下的合作研究的延续。INT-8717920，并为马里亚诺博士目前的研究增加了国际合作的维度。切——8917725。他们之前的合作研究非常成功，并在评审期刊上发表了几篇联合论文。这种成功的合作产生了作为继续进行联合研究的基础的想法。计划在持续合作期间进行的研究应提供有关电子转移光化学（光电化学）新领域的各个方面的知识，以及关于构建复杂分子结构的新的和潜在的有效方法。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。
