Preparation of Nanoscopic Fittings for Organic Nanotubes

随着纳米技术的发展，未来将需要纳米级管道或管道，因此将需要控制纳米级管道内的弯曲。构建这种管道的一种方法是通过控制纳米管的组装。目前已知有几种连接无机纳米管的方法，但没有方法可以连接有机物质；这可能会出现与缺乏有机功能相关的障碍。有机纳米导管非常适合于将其掺入膜中，以控制分子物质的运输或沉积，也适用于对映体的分离。这项由该基金资助的研究的具体目标是设计和开发纳米级配件，以便以90度角连接有机纳米管，形成L形和t形连接。这将通过形成以90度角连接的分子棒（由具有树突外围的卟啉配位聚合物组成），将棒的外围交联，然后将圆柱形结构的中心取心来实现-从而提供具有可控结构的单分子有机纳米管。

As nanotechnology evolves, there will be a need in the future of nanoscopic plumbing or conduit, thus there will be a need for controlling bends within nanoscopic conduit. One method for constructing such conduit is by the controlled assembly of nanotubes. A few methods to joining inorganic nanotubes are known, however, no methods to form fittings for organic substances; this may present snags related to the lack of organic functionality. Organic nanoscopic conduit is well suited for incorporation into membranes for controlled transport or deposition of molecular substances and also for the separation of enantiomers. The specific aim of the research funded by this fellowship is to design and develop nanoscopic fittings in order to joint organic nanotubes at a 90 degree angle to form L and T-shape junctions. This will be achieved by forming molecular rods (composed of a porphyrin coordination polymer with a dendritic periphery) joined at a 90 degree angle, cross linking the periphery of the rod, and then coring out the center of the cylindrical structure-thus providing a unimolecular organic nanoscopic tube with controlled architecture.
