Published on: June 1, 2016

  • Analysis of materials exhibiting responsiveness to stimuli like light, pH, heat, and electromagnetic fields.
  • Discussion of the role of intra- and intermolecular interactions (weak and strong) in material properties.

    • Main Results:

    • Structural flexibility, driven by weak intermolecular forces, is key to self-assembled architectures.
    • Stronger bonds (coordination, ionic, covalent) can create robust yet reversible structures.
    • Advanced materials show significant performance changes in response to external stimuli.

    Conclusions:

    • Structural flexibility and molecular motion in self-assembled nanostructures are vital for "smart" material development.
    • Both weak intermolecular forces and stronger bonds play critical roles in material lability and responsiveness.
    • External stimuli can effectively tune the performance of these advanced nanomaterials.
