From self-assembled toroids to dynamic nanotubules

Supramolecular nanostructures based on self-assembly processes have received considerable attention because these structures can lead to dynamic nanomaterials. Among the diverse self-assembled nanostructures, toroids are interesting nanostructures with the potential for many applications such as channel formation because of their unique symmetrical and annular shape. Notably, a further stacking of the toroids can produce well-defined one dimensional nanotubules with responsive properties triggered by external stimuli such as temperature, ionic strength, and guest molecules. This review introduces recent research in the area of self-assembled nanostructures from toroids to dynamic nanotubules.
