| Outline of Final Research Achievements |
In this study, we created a number of compounds showing unique optical properties based on 5-aminothiazoles, which we originally developed as a nitrogen-containing heterocyclic compound. For example, we revealed that a compound in which a 4-pyridyloxy group is incorporated at the 2-position of thiazole and a bis (4-methoxyphenyl) amino group is incorporated at the 5 position shows mechanochromism. By grinding the compound, the luminescent color changed from the original yellow green color to the orange color fluorescence, and furthermore it returned to the original yellow green color when exposed to acetone vapor. This change in luminescent color was considered to be due to the change of the states from the crystalline state to the amorphous state, and the change could be confirmed by powder X-ray diffraction measurement.
