Achiral pyrene oligomers α show remarkable amplification of chirality (see circular dichroism spectra) in the presence of minute quantities of a chiral inductor χ. Spectroscopy and electron microscopy data support a model in which pyrene oligomers form helical, supramolecular polymers by interstrand stacking interactions.
