Description Helical nanofibers are successfully constructed from suitable self-assembling
pseudopeptide-based molecular building blocks. The handedness of these
nanofibers can be reversed by using mirror-imaged pseudopeptide-based
building blocks. Straight nanofibers are also constructed by modulating the
molecular and supramolecular structures by the proper choice of the
stereochemical nature of the molecular scaffolds. This study demonstrates
that molecular structure and chirality are not the only determining factors
for tuning the morphology and chirality of nanostructures; the nature of the
supramolecular structures formed from the corresponding molecular
scaffolds also plays a key role in dictating the shape and chirality of
nanostructures. Helical nanofibers are suitable templates for fabricating
dipeptide-capped gold nanoparticles, indicating a possible use of these
nanofibers in the construction of arrays of gold nanoparticles.
