Dynamic Control of Spin-Selective Electron Transfer in Donor-Acceptor Arrays

有了这个更新奖，有机和大分子化学项目将继续支持西北大学化学系Michael R. Wasielewski教授的工作。该研究将扩展PI在设计和合成新型分子材料方面的研究，这些材料具有光诱导电子转移产生自由基离子对的能力。利用自由基对的性质受磁场影响这一事实，将加入一个稳定自由基形式的内部磁场。额外的未配对自旋的影响以及开启和关闭这种自旋对电子和自旋转移的能力将被研究。这些研究将提供关于分子内未配对电子自旋之间相互作用的基础知识，这将有助于设计收集太阳能的系统和用于分子光电子学。该项目将为本科生和研究生提供重要培训，重点是妇女和代表性不足的少数民族。

With this renewal award, the Organic and Macromolecular Chemistry Program continues its support of the work of Professor Michael R. Wasielewski of the Department of Chemistry, Northwestern University, Evanston, IL. The research will extend the PI's research on the design and synthesis of novel molecular materials with the capability of undergoing light induced electron transfer to generate radical ion pairs. Taking advantage of the fact that the properties of radical pairs are affected by magnetic fields, an internal magnetic field in the form of a stable free radical will be incorporated. The effect of the additional unpaired spin and the ability to turn this spin on and off on electron and spin transfer will be investigated. These studies will provide fundamental knowledge concerning intramolecular interactions among unpaired electron spins that will aid in the design of systems for harvesting solar energy and for use in molecular optoelectronics. The project will provide important training for undergraduate and graduate students with an emphasis on women and underrepresented minorities.
