Outline of Final Research Achievements

The glucose-based gelators which connected glucose and gallic acid bearing long alkyl chains through amide groups were synthesized. The gelators showed good gelation ability toward halogenated organic solvents, and were able to concentrate the halogenated organic solvent to the gel phase in some binary mixed solvents. Their gelation properties were analyzed by using Hansen solubility parameters (HSP) and we found that intramolecular hydrogen bonding between gelators play an important role in the gel formation toward halogenated organic solvents. The self-assembly behavior of the gelators was also investigated by FT-IR, NMR, XRD, and SEM. These studies revealed that the intermolecular hydrogen bonding between the gelator molecules were the main driving forces for the formation of the gel.

Academic Significance and Societal Importance of the Research Achievements

低分子ゲル化剤のゲル化と溶媒との関係は不明な部分も多く,その関係性の解明は重要な課題である。本研究で用いたゲル化剤では,ゲル化挙動の解釈としてHansen溶解度パラメータの利用が極めて有効であることを明らかにした。ゲル化剤分子構造の最適化により,多くの産業分野で利用されているハロゲン化有機溶媒に対して高いゲル化能を示す低分子ゲル化剤を開発した。これらのゲル化剤を用いたハロゲン化有機溶剤の流出防止剤や濃縮・回収剤への応用の可能性を示すことができた。
