| Outline of Final Research Achievements |
In order to understand how to control and design switchable properties in the crystalline state, we studied the mechanism of reversible crystal-to-crystal transformation of peptide metallo-macrocycles and their effect on gas adsorption behavior. On the basis of detail structural analyses, we found that hydrogen bond switching plays a significant role for cooperative structural change in the crystalline state. The crystalline cavities of peptide metallo-macrocycles exhibited selective CO2 gas adsorption into the narrow cavities accompanying the expansion of the peptide framework. These results suggested that our crystalline peptide metal complexes are an excellent platform for stimuli-responsive materials.
