Coordination Compound, Scanning Probe Microscopy, Synthetic Chemistry
Nanotechnology is the manipulation technique of a molecular scale materials. Our group has focused on coordination complexes as a key materials for bottom-up approaches and developed new materials for innovative green nanodevices. Main research themes are summarized as follows.
- Self-Assembled Supramolecular Coordination Complexes
Coordination polymers are coordination compounds with infinite structures with backbones constructed from metal ions as connectors and ligands as linker. Coordination polymers can be obtained by just mixing metal ions and bridging ligands. The obtained structures are well defined and perfectly ordered. The obtained nanostructures are unique candidate for innovative green materials and nanoelectronics devices. We have synthesized porous coordination materials and nanomagnet.
- Estimation of molecular nanostructures by advanced equipment.
In our group, the nanostructures obtained by self-assembled process are observed by scanning probe microscopy, electron microscopy, and synchrotron radiation experiments. The new nanomaterials are manipulated and precisely estimated by the advanced equipment. For example, we have showed the molecular patterning of single-molecule magnets by using scanning tunneling microscopy. Our molecular system will provide us with a new design strategy for molecule-based spintronics devices.
