Research Outline

This project aims the development of luminescent soft crystals which respond to environmental stimuli such as vapor, light, heat, and mechanical force sensitively and/or specifically. For this purpose, chromic metal complexes, organic p-systems, and supramolecular materials will be further explored and their properties will be investigated in details to elucidate the principals of these phenomena. The collaboration with researchers of various fields as one project team would not only promote the development of new systems of metal complexes, organic molecules, and supermolecules effectively, but also produce new concepts and the breakthrough by the synergetic effects. In addition, such sophisticated stimulus-responsive materials will be applied to fabricate novel devices in collaboration with other teams in this research area. Through the research, this team leads the establishment of science and functionalization of softcrystals.

Luminescent metal-complex crystals which exhibit chromic phenomena
