This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).In this project supported by the Experimental Physical Chemistry Program, Professor Aaron Massari of the University of Minnesota will employ two-dimensional infrared vibrational echo spectroscopy (2D-IR VES) to understand how the molecular motions within conducting polymers influence the mobilities of electrical charges. This research project will utilize polymer samples incorporated into electrode arrays, which will allow for the in-situ study of molecular motions and charge mobilities in polymer structures in the presence of an external electric field. These studies will provide molecule design and polymer processing information that will be immediately relevant to future photovoltaic or molecular electronic technologies that are based on organic molecules.This research project will help to advance not only the aforementioned technologies, but our understanding of structure-function relationships in electronic materials in general. Graduate and undergraduate students involved in the project will receive training in a highly multidisciplinary environment which includes not only laser optics and fundamental molecular spectroscopy, but materials science, electrochemistry, and theory. Prof. Massari will work with on-going programs at the University of Minnesota such as the Multicultural Summer Research Opportunities Program (MSROP) and the Lando Fellowship Program to recruit undergraduate students from area community colleges to participate in chemical research.

该奖项由美国2009年复苏和再投资法案（Public Law 111-5）资助。在这个由实验物理化学计划支持的项目中，明尼苏达大学的Aaron Massari教授将使用二维红外振动回波光谱（2D-IR VES）来了解导电聚合物中的分子运动如何影响电荷的迁移率。该研究项目将利用聚合物样品纳入电极阵列，这将允许在外部电场存在下对聚合物结构中的分子运动和电荷迁移率进行原位研究。 这些研究将提供分子设计和聚合物加工信息，这些信息将与基于有机分子的未来光伏或分子电子技术直接相关。本研究项目不仅有助于推进上述技术，而且有助于我们对电子材料结构-功能关系的理解。 参与该项目的研究生和本科生将在高度多学科的环境中接受培训，其中不仅包括激光光学和基础分子光谱学，还包括材料科学，电化学和理论。 Massari教授将与明尼苏达大学正在进行的项目合作，如多元文化夏季研究机会计划（MSROP）和Lando奖学金计划，从地区社区学院招募本科生参与化学研究。
