Development of Defect-Induced Soft Crystal by Using Ionic Crystal of Belt-Shaped Metal Complex

Keywords

Co-Researcher
Co-Researcher: Shigehisa Akine (WPI Nano Life Science Institute, Kanazawa University, Professor)

Research Outline

This project aims at the development of new soft crystals in which shape-persistent rigid belt-shaped macrocycles were connected through weak interactions. This researcher will synthesize kinds of cationic macrocycles, metallonanobelt, by self-assembly of rigid bent ligands and metal ions, and connect the metallonanobelts through non-covalent interactions to form new soft crystal that have intrinsic pores and can response to external stimuli such as vapor. This project also aims at precise control of the flexibility of the soft crystal by introducing lattice defect. This work can give an important clue for the rational design of soft crystals that have been created accidentally.
