| Outline of Final Research Achievements |
The purpose of this study was to propose environmentally-responsive porous magnets that enable “chemical-physical information conversion” by changing physical properties, especially magnetic properties, under various gas atmospheres. We found a number of complex lattice compounds that change their charge states upon crystalline solvent or gas adsorption/desorption, and clarified the details of the charge transfer and magnetic property switching phenomena. We also succeeded in finding several novel spin-crossover complexes that change their spin states in common small-molecule gases such as carbon dioxide. In experiments under mixed gas atmospheres, we also succeeded in capturing the phenomenon of magnetic transition conversion depending on the mixing ratio under oxygen and nitrogen mixtures, and also found differences in adsorption and magnetic phase conversion between carbon dioxide and acetylene.
