| Outline of Final Research Achievements |
In this study, we developed metal-organic frameworks (MOFs) with redox-active properties, including MOFs composed of 2,5-dihydroxy-1,4-benzoquinone (dhbq) ligands and their analogues, as well as MOFs composed of lanthanide phthalocyanine derivatives. Regarding the MOFs composed of dhbq ligands, we successfully synthesized three novel MOFs: Fe(dhbq)(H2O)2, Fe2(dhbq)3, and M(dhbq)(bpy). In the case of lanthanide phthalocyanine complexes, we achieved an electrochemical metal-semiconductor transformation while maintaining the single crystal structure. Particularly, we discovered a phenomenon attributed to the phase stability of Ce3+ and Ce4+ in the MOF composed of cerium ions.
