Research Outline

Vapochromism is one of the interesting phenomena of soft crystals. In metal complexes exhibiting vaporpochromism, the structural change of the host due to vapor adsorption triggers the color change, and development of highly functional vaporochromic materials can be expected by controlling the host structure formed by the metal complex. The research subjects are development of solid-state NMR methods for analyzing local structure, dynamics, and electronic state in vapochromic metal complex and analysis of local structural change in vapochromic metal complex due to vapor adsorption. X-ray structure analysis and theoretical calculation are added to solid-state NMR analysis to elucidate the mechanism of vapochromism and provide useful information for material design. The developed solid-state NMR methods will be utilized for the development of the vapor-chromic metal complex having multi-step color change properties.
