Introduction

One of the important features of metal complexes is reversibility of metal-ligand coordination bonds. This enables the spontaneous formation of supramolecular structures and the dynamic conversions in response to external stimuli. In order to make and convert large-sized supramolecular structures in a desired fashion, it is important to place appropriate metal ions and organic ligand moieties in a suitable arrangement. Therefore, we need to select suitable metal ions and need to finely design organic molecules with appropriate ligating moieties.

Our group aims to develop novel dynamic functional metal complexes and responsive supramolecules by utilizing dynamic feature of metal ions and fine design of organic frameworks. Please visit the following links where you can find our research overviews with ANIMATION effect!
