Outline of Final Research Achievements |
It is difficult to change the photochromic properties in the crystal, because they depend on the initial structures of the compounds. One of our challenges is to create new crystalline materials that have in-situ control of photochromism. Thus, we designed and synthesized new hybrid type cobaloxime complexes using photochromic compounds. In the crystals, photochromism changed dynamically in association with the crystalline-state photoisomerization of cobaloxime complexes and retaining a single crystal form. In this study, new photochromic complexes and the relationships between the structure-dependent photochromic moiety and the isomerization reaction of such complexes in the crystalline state were investigated. As a result, the photochromic moieties were modified by the crystalline-state photoisomerization of cyanoethyl group, which successfully enabled the in-situ control of photochromism. This result is expected to contribute to the future development of photochromic materials.
