| Outline of Research at the Start |
A library of novel molecules (or monomers) with thermodynamic incompatible side chains has been designed and synthesized. Supramolecular polymers are formed via “salt-bridge” interaction between. Multiple ordered nano-phase structures have been observed in the solid-state supramolecular polymers.

| Outline of Annual Research Achievements |
I've successfully developed polymeric materials featuring sub-5nm periodic structures, utilizing solid-state supramolecular polymers. These polymers are assembled from supramolecular monomers, each comprising a carboxylate group, a guanidinium group, and two thermodynamically incompatible oligomers. Through 'salt-bridge' interactions between guanidinium and carboxylate, supramolecular polymerization is facilitated. Confirmation of nanoscale hierarchical structures was achieved via small-angle X-ray scattering and transmission electron microscopy. These polymeric materials, boasting hierarchical structures, exhibit a storage modulus over 26 times higher than their polymer-blending counterparts, which lack ordered structures.
