Salting Reactive Organic Intermediates

这项研究的重点将是在室温下稳定卡宾和自由基对，它们没有提供特别的分子内空间或电子稳定。这一方法依赖于1，3，6-三磺酸基吡喃(TSP)的使用，并将其结合到硫酸钾单晶中。TSP的单晶光学和电子顺磁共振研究将被用来理解两个化学问题：(1)室温磷光的机理；(2)单晶染料激光器中三重态的有害布居。通过这一奖项，有机和高分子化学项目支持了华盛顿大学化学系的Bart E.Kahr博士的研究。卡尔教授将专注于开发一种方法，用于在室温下分离惰性单盐晶体中定向的、反应的/亚稳定的有机分子的基质。

The focus of this research will be to stabilize carbenes and radical pairs at room temperature which are afforded no particular intramolecular steric or electronic stabilization. The methodology relies on the use of 1,3,6-trisulphonated pyrenes (TSPs) incorporated into potassium sulfate single crystals. Single crystal optical and EPR studies of TSPs will be applied to the understanding of two problems in chemistry: (1) the mechanism of room temperature phosphorescence, an (2) the deleterious population of triplet states in single crystal dye lasers. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Dr. Bart E. Kahr of the Department of Chemistry at the University of Washington. Professor Kahr will focus his work on developing a method for the matrix isolation of of oriented, reactive/metastable organic molecules in inert single salt crystals at room temperature.
