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导管，因此将需要控制纳米级导管内的弯曲。一种用于构造这种管道的方法是通过纳米管的受控组装。一些连接无机纳米管的方法是已知的，然而，没有形成有机物质的配件的方法;这可能存在与缺乏有机官能团有关的障碍。有机纳米管道非常适合并入膜中用于分子物质的受控运输或沉积，并且还用于对映体的分离。该奖学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和T形结。这将通过形成以90度角连接的分子棒（由具有树枝状外围的卟啉配位聚合物组成），交联棒的外围，然后将圆柱形结构的中心取芯从而提供具有受控结构的单分子有机纳米管来实现。

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.
