Synthesis of soft octahedral nanoparticles through supramolecular self-assembly of C3‑symmetric trinaphthylamine trisamides
Self-assembly of C3-symmetric - triarylamine - trisamide monomers has been recently studied in the literature, consistently leading to supramolecular polymers and materials with remarkable optical - and electronic properties.

| Summary: | Self-assembly of C3-symmetric - triarylamine - trisamide monomers has been recently studied in the literature, consistently leading to supramolecular polymers and materials with remarkable optical - and electronic properties. As observed with other families of C3-symmetric monomers, their nucleation and growth - mechanisms mainly rely on their one-dimensional stacking through highly - directional hydrogen bonding. Now, we report the possibility of shifting - their directing noncovalent interactions from hydrogen bonding to - π-π and van der Waals interactions and, consequently, - of shifting their self-assembly from one-dimensional fibrils toward - two-dimensional smectic layers that further organize in purely organic - octahedral nanoparticles. This dramatic structural change is simply - achieved by extension of the aromatic core from phenyl to naphthyl - units. Interestingly, the size of these soft supramolecular octahedra - can be controlled between 200 nm and 50 μm by choosing the cooling - rate used during the self-assembly process. By employing a comprehensive - combination of experimental and theoretical tools, we fully elucidate - the hierarchical mechanisms at work in the octahedrons’ formation. - These results highlight the potential tunability of C3-symmetric H-bonded monomers to generate original 3D - supramolecular systems and materials. |
