Outline of Final Research Achievements

In this study, we have established a series of versatile techniques to lead 1-dimensional nanostructures via high energy charged particle induced chemical reactions, particularly the polymerization of organic molecules within nm-sized cylindrical particle tracks. The technique is referred as Single-particle Triggered Linear Polymerization (STLiP). Long chains in polymers that can variously change their conformations dominantly determine the characteristics and advantages of polymer materials such as mechanical property, thermal stability, solubility and processability, and so on. Since the radius of gyration for a polymer chain is in the range of several nanometers, it has been a more suitable target than a small molecule to characterize its conformation and size. The 1-dimensional nanostructures derived from the present study have been successfully demonstrated as the key material platforms for opto-electronic and/or sensing devices, reflecting their extraordinary wide surface area.
