In this study, I aim to synthesize water-soluble nanosheets by extending the 2D nanosheet synthetic strategy that I have been developed. Water-soluble organic nanosheets can not be prepared by using dynamic covalent bonds. In addition, I am also investigating the self-assembly of nanosheets by introducing carboxylic acids in the nanosheets. I hope to find the seeds of my own research during this research period.
The use of dynamic covalent bonding is effective for the synthesis of two-dimensional organic nanosheets. However, the reversibility leads to a lack of water resistance of the prepared nanosheets. In this study, we developed a nanosheet synthesis method using covalent bond formation. In addition, we aimed to impart water solubility to the nanosheets. The nanosheets were synthesized in liquid phase, and their formation was confirmed through various microscopic observations and powder X-ray diffraction. These nanosheets do not decompose in water. Attempts to convert the introduced CN groups into carboxylic acids in the nanosheets suggested partial conversion to amide groups as reaction intermediates. Optimization of the conditions would provide insights toward achieving water-soluble nanosheet synthesis.
