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保罗·芭芭拉（Paul Barbara）教授得到了理论和计算化学计划的支持，该计划研究了有机聚合物膜的单分子光谱，包括荧光共轭聚合物，包括聚苯基 - 乙烯聚合物。 在其他要检查的系统中，有光驱动的聚合电动机和模型的单分子光子设备。 聚合物构象，构象松弛，光体物理学和链链相互作用是其中的一些问题。 如在LED设备中，应制备超纯电导电聚合物，并在有电荷的情况下研究其光体物理学。 PI提议尝试在这些单分子上尝试使用飞秒时间分辨的测量。要研究的材料在电用量，光电和光伏应用中很重要。
