Electronically Conducting Organometallic Polymers

本项目由中国科学院本科院校科研项目（RUI）无机、生物无机和有机金属化学项目资助，该项目旨在通过提高本科院校学生的科研质量，加强他们的科学技术培训，为科学研究奠定广泛的基础。该项目将涉及电子导电有机金属聚合物的合成，其中一些聚合物可能会在结合小分子时改变其电学性质，因此可以作为这些分子的传感器。带有附加吡咯基团的茂金属可以用来形成不同长度的导电聚合物。各种分析技术将被用来表征聚合物和分子建模方法将被用来关联物理和电子性质。一个特别的目标是确定这些聚合物是否能够以可逆的方式进行环滑动以协调小分子，如CO，从而导致电导的变化，从而允许这些材料用作传感器。本科生将在RUI活动的支持下进行多学科研究，目标是开发新的导电材料作为小分子（如一氧化碳）的传感器。？%¢/│？0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00¥©Á¢Á│/¥/% '¥╣│¾¾Â/│Á¢// <s:1> /ÀÁ ？¢-萨拉吉Â/│Á¢Á¢╣¥╣├Á╣¢¥萨拉吉_Á¥/% _Á¥©？′′？╝,

This project is being supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program under the Research in Undergraduate Institutions (RUI) activity, which is part of the Foundation's effort to help assure a broad base for scientific research through enhancing the scientific and technical training of students in undergraduate institutions by involving them in high quality research. This project will involve the synthesis of electronically conducting organometallic polymers, some of which may change their electrical properties upon binding small molecules and so serve as sensors for these molecules. Metallocenes with attached pyrrole groups will be used to form conducting polymers of varying lengths. A variety of analytical techniques will be used to characterize the polymers and molecular modelling methods will be used to correlate physical and electronic properties. A particular goal is to determine whether these polymers can undergo ring slippage to coordinate small molecules, such as CO, in a reversible fashion that will cause a change in conductance and so would allow these materials to be used as sensors. Undergraduates will perform multidisciplinary research supported under the RUI activity with the goal of developing new conducting materials as sensors for small molecules, such as carbon monoxide. ?%¢ /┤ ?╝À/╣│ /│╣┤¢ ? ¥©Á¢Á │/¥/%`¥╣│ ¢┐╝Â/│Á¢ /┤ / ▓╝?/┤ ╝/ÀÁ ? ¢┐╝Â/│Á ¢Á¢╣¥╣└Á ╣¢¥╝┐_Á¥/% _Á¥©?┤¢ ┴╣%% ▓Á ┐¢Á┤ ╣ ¥©╣¢ ┴?╝,
