| Outline of Final Research Achievements |
When a matter is not superposable on its mirror image, as in the case of right and left hands, the geometry of the matter is referred to as "chiral". Chirality is an important characteristic of molecules and nanomaterials. In this research, we developed and/or advanced the methods combining microscopy with optical activity spectroscopy, which characterizes molecular- and nano-level chirality, and we utilized them to investigate fundamental properties of local chirality of nanomaterials, and to apply the knowledge to develop novel chiral photo-chemical functions of materials. We have shown that local chirality properties of nanomaterials show fundamentally different behaviors as compared with those observed with conventional macroscopic optical activity spectroscopy. By the properly designed usage of noble metal nanostructures and polarized optical fields, we found that molecular- and/or nano-scale chirality can be induced on achiral materials systems.
