Outline of Final Research Achievements

Layared double hydroxides (LDHs) intercalated with aromatic anions are able to selectively take up non-ionic aromatics from aqueous solutions. This is attributed to the extent of aromatic interactions between the aromatic rings of the intercalated aromatics and the aromatics in the aqueous solutions with different electronic density, i.e., the different adsorption of the various aromatics is probably caused by differences in the extent of the π－π stacking interactions.

Academic Significance and Societal Importance of the Research Achievements

有機修飾LDH、有機修飾MMTによる非イオン性有機化合物の選択的認識・捕捉は、活性炭等では実現できないため、非常に斬新なアイディアである。この研究の進展により、高選択性・高感度な非イオン性有機化合物のセンシング・捕捉材料の開発が期待できる。
排水処理という従来の方法ではなく、化学工場や製紙工場、食品工場等の排水中からの有価な非イオン性有機化合物の回収という新規な方法を提案することができる。
