| Outline of Final Research Achievements |
This research aimed at a fabrication of novel anisotropic materials from renewable resources and an establishment of a method to analyze their structures. The 31P chemical shift tensor for phenylphosphonic acid (PPA) was successfully determined by a combination of a magnetic alignment and standard procedure of the single-crystal rotation method in solid-state NMR spectroscopy, indicating that the magnetic alignment can provide a powerful means of determining all of the information on 31P CSA from a microcrystalline powder. On the other hand, the alignment of poly(L-lactic acid) (PLLA) crystals was also achieved by epitaxial growth on a magnetically-oriented nucleating agent. Cellulose nanocrystal, of which surface is chemically treated, can be expected as a substrate for alignment of PLLA via crystal growth on the surface.
