Nanomechanical Function Arising from the Complex Architecture of Dendronized Helical Polymers

  • Jonathan G. Rudick
Part of the Advances in Polymer Science book series (POLYMER, volume 262)

Abstract

Dendronized polymers that have a cylindrical shape and a helical polymer backbone at the core of the cylinder are able to undergo reversible stretching and contraction of the helix. As the helix expands, the cylindrical macromolecule elongates like a molecular mechanical actuator. When the polymers are self-organized in a columnar lattice, the cylinders can be aligned and the extension of the individual molecules is amplified to macroscopic dimensions and can be employed to perform work. Relationships between the complex architecture of these polymers, their organization in bulk, and emergent function are discussed as an example of the remarkable opportunities that remain to be explored as we commemorate the 60th anniversary of Hermann Staudinger receiving the Nobel Prize for Chemistry.
