| Outline of Final Research Achievements |
Photochemical behavior of cyanine, viologen, bipyridine, porphyrin derivatives were examined for the samples in water and on clay nanosheet. As a results, for molecules having rotatable parts exhibited strong emission enhancement. Judging from the fluorescence quantum yield and excited lifetime, the increase of kf or the decrease of knr could be the reason for the fluorescence enhancement.
