| Outline of Final Research Achievements |
In this project, we studied the intermolecular interactions between perfluoroalkyl (Rf) compounds and heterogeneous molecules. As a representative result, we found a characteristic property of liquid perfluoroalkanes on the water surface: those remain on the water surface for a long time. This result indicates that perfluoroalkane molecules have a good affinity at the air-water interface, although Rf compounds are known to have a low affinity to water in general. This property does not appear in non-fluorinated organic solvents. As a result, the specific character of perfluoroalkanes on the water surface is surely attributed to the molecular interactive force derived from the large dipole.
