| 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.
