| Outline of Final Research Achievements |
The VCD spectroscopy was applied to reveal the kinetic and thermodynamic aspects of gelation by a chiral low molecular gelator with perfluoroalkyl groups. An attention was paid to the helical nature of a perfluoroalkyl chain on the formation of gel fibrils. It was noted that VCD signals were remarkably enhanced during the gelation process. The three-dimensional gelation was compared with the formation of a two-dimensional Langmuir-Blodgett (LB) film. Some thicker rods with helical grooves were observed in the LB films, which were regarded as a precursor of gel fibrils.
