Research Project

Coordination asymmetry materials produced by on-site recrystallization method

Co-Investigator

Satoshi Watanabe (Assistant professor, Faculty of Advanced Science and Technology, Kumamoto University)

Abstract

We develop two-dimensional (2D) nanosheets of crystalline coordination frameworks (SURMOF) on a well-defined surface as a coordination asymmetry system. We found that an acetic acid vapor environment dramatically decreased the activation energy and accelerated the recombination of coordination bonds between metal ions and carboxylate ligands in metal-organic frameworks. Ultimately, two-dimensional horizontal crystal growth was induced to form monomolecular sheets as the most thermodynamically stable crystal structure on a surface.
