A photo/chemo dually interconvertible system was constructed through the supramolecular assembly of azobenzene-diphenylalanine (Azo-FF) with α-cyclodextrin. The resultant chiral nanohelix able to interconvert into a nanosquare upon irradiation at different wavelengths, but nanofiber changing solvent polarity, which provides feasible way achieve highly ordered nanostructures various morphologies, dimensions and chiralities.
