129Xe NMRを利用した大環状化合物からなるカラムナー液晶中の孤立空間の解析

抄録

Nanopore materials with fluidity show promise for novel chemical events such as the accommodation, unique arraying, and chemical reactions of guest molecules, which could potentially lead to new insights and developments in this field. It appears that columnar liquid crystals composed of shape-persistent macrocycles may form nanochannels due to the intrinsic nanospace in the column. However, the existence of substantial nanoporosity has not been investigated experimentally. In this study, we confirmed the presence of discrete and spatiotemporally continuous voids in a liquid-crystalline material using 129Xe NMR spectroscopy.
