This award is made by the Office of Special Projects in the Chemistry Division under the Materials Synthesis and Processing Initiative. This research will optimize the photochemical generation of phenoxy free radicals with regard to the type of substitution and the irradiation wavelength employed and apply the methodology to study electron exchange-controlled magnetic interactions in both molecular and polymeric systems. Solid state stable phenoxy polyradical systems will also be prepared and magnetic interactions in the solid state will be determined using spectroscopic and magnetic susceptibility techniques. %%% These fundamental structural and mechanistic investigations are directed towards developing rules to describe magnetic interactions both within and between molecules which may permit the design of a new generation of bulk organic ferromagnets.

该奖项由化学司特别项目办公室在材料合成和加工倡议下颁发。这项研究将根据取代类型和所采用的照射波长来优化苯氧基自由基的光化学生成，并应用该方法学来研究分子和聚合物体系中电子交换控制的磁相互作用。还将制备固态稳定的苯氧基多自由基体系，并将使用光谱和磁化率技术确定固态中的磁性相互作用。这些基本的结构和机理研究旨在开发描述分子内部和分子之间的磁性相互作用的规则，这可能允许设计新一代块状有机铁磁体。
