Outline of Final Research Achievements

Two-component low molecular weight gelators have been developed from the salts of achiral diamines and chiral dicarboxylic acids derived from a natural amino acid. Organic solvents such as toluene were well gelated by these salts. It was shown that suitable balance between hydrophobicity of the alkyl group and hydrophilicity of the hydrogen-bonding group was important for the gelation ability. It is indicated that the molecules self-assembled to form a layered structure. The supramolecular gel enabled enantioselective extraction of one enantiomer of the alcohol from its racemate despite of low efficiency.
