  • Solution studies using concentration and temperature dependence, dynamic and static light scattering.
  • Surface characterization using Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM).

    • Main Results:

    • Dendritic substituents induced face-to-face rotated pi stacking, leading to binding constants of 1.2 x 10(5) and 1.7 x 10(5) M(-1).
    • Formation of rod-like supramolecular structures (nanofibers) in aqueous solution, transferable to surfaces.
    • TEM and AFM confirmed long fibers (micrometers long, ~70 nm diameter), some with ribbon-like characteristics and chiral rope-like structures for compound 1b.
    • Successful intercalation and temperature-triggered release of Disperse Orange 3 dye within the filaments.

    Conclusions:

    • The synthesized amphiphiles self-assemble into well-defined supramolecular nanofibers driven by pi-stacking and dendritic interactions.
    • The self-assembled structures exhibit tunable properties and can be utilized for guest molecule encapsulation and release.
    • These findings highlight the potential of oligo(phenylene ethynylene) amphiphiles as building blocks for advanced functional materials.
