Outline of Annual Research Achievements |
A general route for the synthesis of asymmetric catenanes with multiple, different functional groups was established. There were many synthetic challenges involved in the synthesis. For example, the solubility of the key intermediates needed to be finely tuned, and the compatibility of various protecting groups required careful consideration. Now a variety of catenanes with asymmetric rings can be readily synthesized.
As for the formation of MOF, it was found that the functional groups in catenane ligand affect the formation of the crystal, as well as the morphology of the crystal. However, crystals which are good enough for further characterization have not been successfully obtained.

Current Status of Research Progress |
Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
The design and synthesis of suitable catenane ligands are the first major challenge of the project. Given the difficulty of the synthetic work, longer time may be required to understand the system.
|
Strategy for Future Research Activity |
Catenane ligands with diverse functional groups will be synthesized in order to understand how the property of functional groups affect MOF formation. We aim to find the best combination of functional groups which can produce MOF crystals that are robust enough for further characterization.
|
Causes of Carryover |
The synthetic work took time and has been challenging. As a result, the progress of the project was relatively slow.
The remaining funding will be used to continue the project.
