| Research Abstract |
This research aimed at a fabrication of novel anisotropic materials from cellulose and an establishment of a method to analyze their crystal structures by X-ray/neutron diffraction and solid-state NMR spectroscopy. The three-dimensional alignment of microcrystals was achieved for model organic compounds of low-molecular weight by using a frequency-modulated rotating magnetic field. It was demonstrated that the crystal structures can be analyzed through the evaluation of 13C and 31P chemical shift tensors even from microcrystalline state. The orientation of cellulose was performed by application of a magnetic field for cellulose nanocrystals which were obtained through mechanical homogenization followed by acid hydrolysis of original cellulose materials.
