Professor Paul Barbara of the University of Texas at Austin is supported by the Theoretical and Computational Chemistry Program to study single molecule spectroscopy of organic polymer films, including poly-phenylene-vinylene polymer, a fluorescent conjugated polymer. Among the other systems to be examined are photo-driven polymeric motors and model single-molecule photonic devices. Polymer conformation, conformational relaxation, photophysics and chain-chain interactions are some of the issues. Ultrapure conducting polymers are to be prepared and their photophysics studied in the presence of charges, as in a LED device. The PI proposes to attempt femtosecond time-resolved measurements on these single molecules.The materials to be studied are important in electro-optic, opto-electronic and photovoltaic applications.

德克萨斯大学奥斯汀分校的Paul Barbara教授得到理论和计算化学计划的支持，研究有机聚合物薄膜的单分子光谱，包括聚亚苯基-亚乙烯基聚合物，一种荧光共轭聚合物。 在其他系统中要检查的是光驱动的聚合物马达和模型单分子光子器件。 聚合物构象、构象弛豫、几何物理和链-链相互作用是其中的一些问题。 制备超纯导电聚合物，并在电荷存在的情况下研究它们的电子物理学，如在LED器件中。 PI建议尝试对这些单分子进行飞秒时间分辨测量，所研究的材料在电光、光电和光伏应用中非常重要。
