Link spacer controlled supramolecular chirality of perylene bisimide-carbohydrate conjugate

Abstract

Controllable supramolecular chirality based on the self-assembly of the perylene bisimide-carbohydrate conjugates was achieved, which exhibited right-handed chirality under the triazole as the linker, and left-handed chirality with the amide bond as the linker, because of the difference of the chirality transfer induced by the different π⋯π stacking interactions and the additional hydrogen-bonds of the amide bond.
