With funding from the Organic Dynamics Program, Professor Gibson of Virginia Polytechnic Institute and State University will develop the methodology of self assembling rotaxane systems into supramolecular structures. This methodology depends on the host-guest relationship between bipyridine salts and 32-crown-10 ethers. Once assembled, the structure will be stabilized with covalent bond formation. A myriad of structural motifs is planned and incudes linear, branched and ultimately dentritic type architecture. These types of systems hold promise for new ventures in the areas of photo and electro devices, catalysis and mass transport media. A new class of supramolecular structures is planned from the self assembly of rotaxanes and crown ethers. Once assembled and fixed via covalent bond formation, these types of structures can be explored for their photo and electro device properties. Further, they are anticipated to have catayltic properties and may be used as a mass transport media. + Ûª▓ ÑOh ª' +'ª▒0 Ý + ] $ H l + ¢ ╗ S u m m a r y I n f o r m a t i o n ( ++++++++++++ Û ++++++++++++ ++++++++++++ ++++++++++++ D h + F÷t ─- +F +V 9V=rRv ─+ 9FevH─ª + R:\WWUSER\TEMPLATE\NORMAL.DOT

在有机动力学项目的资助下，弗吉尼亚理工学院和州立大学的Gibson教授将开发自组装轮烷系统成超分子结构的方法。这种方法依赖于联吡啶盐和32冠-10醚之间的主客关系。一旦组装，结构将稳定共价键的形成。无数的结构主题被规划，包括线性、分支和最终的树突状建筑。这些类型的系统在光电设备、催化和大众传输介质等领域为新的企业带来了希望。从轮烷和冠醚的自组装中规划了一类新的超分子结构。一旦通过共价键形成组装和固定，这些类型的结构就可以探索其光和电子器件特性。此外，预计它们具有催化性能，并可用作质量传输介质。+ Uª▓能剧ª“+”ª▒0 Y + ] $ H l + ¢ ╗y S u m m r f I n o r m t I o n ( ++++++++++++ U ++++++++++++ ++++++++++++++++++++++++ D h + F÷t─- +F +V 9V=rRv─+ 9FevH─ª+ R:\WWUSER\TEMPLATE\NORMAL。点
