| Outline of Final Research Achievements |
Organofluorine compounds represented by Teflon are widely used for convenient purposes in daily smart life. Understanding of material properties, however, has long been enveloped in darkness, since correlation between the properties and the molecular primary structure has been unclear. Recently, stratfied dipole-arrays (SDA) theory has proposed to fully explain the correlation lucidly, with which inappropriate objections can theoretically be rejected. To confirm the SDA theory, many experiments are performed, and in the present study, Raman optical activity (ROA) microscope has been developed to reveal spontaneous molecular aggregation of perfluoroalkyl compounds. The beautiful results straightforwardly supports the SDA theory in terms of spectroscopy.
