Reactions in Organized and Constsricted Systems

这个有机动力学项目的奖项是为了支持圣母大学J. Kerry Thomas博士的研究。本研究将集中于有组织的组装体中光诱导的电子转移和光产生的阳离子的后续反应。使用的技术将是激光闪光光解，其中离子事件由短而强烈的闪光引发，并通过快速吸收和发射光谱和传导方法监测产生的短寿命自由基和阳离子。长寿命产品将通过传统的分析方法进行监测，如核磁共振、红外和电子光谱、高效液相色谱和气相色谱。本研究将探讨阳离子的生成方法、溶剂对阳离子反应的影响、增加电荷分离或减少反反应的方法、光诱导的电子转移、导电聚合物在电荷分离过程中的应用、新的宿主系统和聚合物薄膜的光动力学。

This award, in the Organic Dynamics Program, is made to support the research of Dr. J. Kerry Thomas at Notre Dame University. The research will focus on photo-induced electron transfer in organized assemblies and the subsequent reactions of the photo-produced cations. The techniques used will be laser flash photolysis, where the ionic events are initiated by short, intense flashes of light, and the short-lived radicals and cations produced are monitored by fast absorption and emission spectroscopy and conduction methods. Long-lived products will be monitored by conventional analytical methods such as NMR, IR and electronic spectroscopy and HPLC and gas chromatography. The research will explore methods of generation of cations, solvent effects on the reactions of the cations, methods of increasing charge separation or decreasing back reaction, photoinduced electron transfer in onium salts, use of conducting polymers in the charge separation process, new host systems, and photodynamics in polymer films.
