| 摘 要： | A new hydrogelator,pyridinium bromide salt of N-6-bromohexanoyl-L-phenylamino octadecane,was synthesized.Supramo- lecular hydrogels can be formed through the self-assembly of this hydrogelator in water.In this work,D_2O was used instead of H_2O as solvent for FT-IR measurement due to the fact that it is impossible to obtain useful FT-IR information on the hydrogen bonding in water.The investigation of FT-IR and steady-state fluorescence indicated that the driving forces for the self-assembly were mainly hydrogen bonding and hydrophobic interaction.Based on the data of XRD and molecular modeling,the possible mechanism of the formation of hydrogelator aggregates was proposed.
