We show distinct CH-π interactions and assembly pathways for the amphiphile -(fluorenylmethoxycarbonyl)-galactosamine and its epimer -(fluorenylmethoxycarbonyl)-glucosamine. These differences result in the formation of supramolecular nanofibrous systems with opposite chirality. Our results showcase the importance of the carbohydrates structural diversity for their specific biointeractions and the opportunity that their ample interactome offers for synthesis of versatile and tunable supramolecular (bio) materials.
