Multi-Spin Interactions and Dynamics for Organic Spintronics

有了这个更新奖，化学结构，动力学和机制计划继续支持迈克尔R。西北大学的Wasielewski在一个项目中涉及控制有机多自旋系统中自旋相互作用和动力学的因素的研究。 在这些研究中，有机自由基的光激发将被用来产生多自旋系统，这些系统将被光学和微波脉冲技术操纵，以研究它们的自旋动力学。这些多自旋系统在定制的共价有机结构中的性质将被研究，以确定它们的自旋动力学是否可以用来控制自旋极化输运。这些实验旨在控制多自旋系统中的自旋动力学，将有助于理解影响有机分子中电子通信的基本因素，这些研究有可能在光捕获技术、能量存储和量子计算机的发展方面做出重大贡献。 该项目将培训学生掌握现代光谱和合成技术。 与惠顿学院的Mark P. Niemczyk教授合作将使该学院的本科生能够参加该项目。

With this Renewal Award, the Chemical Structure, Dynamics, and Mechanisms Program continues to support Michael R. Wasielewski of Northwestern University in a project involving investigations of the factors controlling spin interactions and dynamics in organic multi-spin systems. In these studies, photoexcitation of organic radicals will be used to generate multi-spin systems which will be manipulated by optical and microwave pulse techniques to study their spin dynamics. The properties of these multi-spin systems in tailored covalent organic structures will be investigated to determine if their spin dynamics can be used to control spin polarization transport. These experiments, aimed at controlling the spin dynamics in multi-spin systems, will contribute to an understanding of the fundamental factors affecting electronic communication in organic molecules.These investigations have the potential to make major contributions in light harvesting technology, energy storage and the development of quantum computers. The project will train students in modern spectroscopic and synthetic techniques. Collaboration with Professor Mark P. Niemczyk of Wheaton College will allow undergraduate students from that institution to participate in the project.
