The 2,13‐dimethoxy[5]helicene–spermine ligand 8 b possesses an axial chirality. The racemic 8 b was bound to B ‐DNA by the accompanying induction of its ( P )‐chirality together with the B ‐to‐ Z helicity change of the duplex DNA, [(dC‐dG) 3 ] 2 . The ( P )‐chirality of the bound 8 b , in turn, transitioned to the ( M )‐chirality according to the Z ‐helicity of the DNA. These results illustrate the chirality synchronization between the DNA and the ligand.
