The Macromolecular, Supramolecular and Nanochemistry (MSN) program of the Division of Chemistry will support the research program of Prof. Norbert Scherer of the University of Chicago. Prof. Scherer and his students will investigate how light could be used to control the plasmonic behavior of metallic nanowire systems. Combining theoretical work and simulations with spectroscopic measurements, the team of investigators will strive to achieve coherent control of plasmon propagation in nanowires and nanowire interferometers, and to create delocalized excitons by coupling quantum dots with silver nanowires. The resulting new plasmonic-coupled materials will advance fundamental ideas for sensing, information and energy transport, computing and perhaps (solar) energy harvesting. The integrated program could lead to new functions of nanomaterials, such as nanolensing and excitonic coupling over long distances, and to the development of linear and nonlinear optical nanoscale circuits. The experimental, theoretical and intellectual challenges of the proposed research will provide a rich environment for graduate student and postdoctoral training in nanoscience and nanotechnology.

化学系的大分子，超分子和纳米化学（MSN）计划将支持芝加哥大学的诺伯特谢勒教授的研究计划。谢勒教授和他的学生将研究如何利用光来控制金属纳米线系统的等离子体行为。将理论工作和模拟与光谱测量相结合，研究人员团队将努力实现纳米线和纳米线干涉仪中等离子体传播的相干控制，并通过将量子点与银纳米线耦合来产生离域激子。由此产生的新的等离子体耦合材料将推进传感，信息和能量传输，计算以及（太阳能）能量收集的基本思想。该综合计划可能导致纳米材料的新功能，如长距离的纳米透镜和激子耦合，以及线性和非线性光学纳米级电路的发展。拟议的研究的实验，理论和智力挑战将提供一个丰富的环境，研究生和博士后培训纳米科学和纳米技术。
