| Outline of Research at the Start |
Single crystals are typically rigid and fragile. Building on the applicant’s recent discovery, in this work, we would like to explore the possibility of rational design of elastic, responsive single crystalline materials by using metal-organic framework containing mechanically interlocked molecules.
|
| Outline of Annual Research Achievements |
We have gained a better understanding of the overall synthetic process used to create asymmetric catenanes. The yield of the desired catenane molecule is influenced by the electronic properties of the reactants.
The crystal structure of an asymmetric catenane ligand was obtained. Structural disorder was observed, suggesting a diverse packing in the solid state due to the molecule's asymmetric property.

Current Status of Research Progress
4: Progress in research has been delayed.
Reason
The synthesis of catenane ligands is challenging in its own right. It took time to optimize the reaction condition and understand how the new molecules packed in the solid state.
|
| Strategy for Future Research Activity |
New ligands will be designed in order to reduce the disordered packing in the solid state.
