Abstract 

Depending on the gelator N-hexyl-2, 4-(3, 4-dichlorobenzal)-D-gluconic amide, three new gelators were synthesized. The butyl acetate gel of the four gelators all had thixotropy by rheology tests. However, the butyl acetate gel of gelator N-(3-propoxy)-propyl-2, 4-(3, 4-dichlorobenzal)-D-gluconic amide can over recover, others gel just can partly recover. IR and fluorescence spectra were used to test these gels. The results showed that the hydrogen-bonds in the butyl acetate gel of gelator D increased after recovery, because the oxygen atom in the side chains of the gelator became new donors of hydrogen-bond in the recovery process. The π-π stacking in the gels decreased, so the butyl acetate gel of other three gelators cannot full recover.
