Dual dynamic chirality generated in the assembly of three achiral rods through the three- fold twisting of a macrocycle

We demonstrated dynamic chirality based on assemblies of three achiral rods with a twisted macrocycle. The three-fold twisting of a macrocycle can lead to two different chiral forms with C-2- or D-3-symmetry. Through a transmission of chirality to each dynamic chiral form, a helical-sense preference was successfully induced.
