Recently, we have explored novel amphiphilic block molecules based on rigid aromatic segments that self-assemble into various supramolecular structures in aqueous solution. For example, we have shown that incorporation of a conjugated rod into an amphiphilic dumbbell-shaped molecular architecture gives rise to the formation of helices, 2-D networks, porous capsules, consisting of hydrophobic aromatic cores surrounded by hydrophilic flexible chains. We have also shown that rod building blocks in rigid-flexible macrocycles self-assemble into discrete barrel or long tubular structures depending on the relative rod volume fraction. In recent publications, we have also demonstrated that aromatic coordination polymers self-assemble into dynamic helical structures with tunable pitch. In this seminar, these results to construct tunable nanostructures will be discussed together with their functional implications. |
