该奖项由特别项目办公室颁发， 材料合成与加工化学部 倡议这项研究将优化光化学 苯氧基自由基的产生， 取代和所采用的照射波长，并应用 研究电子交换控制的磁 分子和聚合物系统中的相互作用。固体 还将制备状态稳定的苯氧基多自由基体系 以及固态下的磁相互作用 使用光谱和磁化率技术。 %%% 这些基本的结构和机理研究是 旨在发展规则来描述磁性 分子内部和分子之间的相互作用可能允许 新一代块状有机铁磁体的设计。

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.
