Hexapyrrole‐α,ω‐dialdehyde , which has eight donor atoms, afforded a dipalladium(II) single helicate (see picture; Pd pink, O red, N blue). A rapid interchange of the helical screw was slowed down by imine formation at the terminal aldehyde units with ( R )‐(−)‐1‐cyclohexylethylamine, leading to an overwhelming excess of a P ‐helical screw. This stable dinuclear single helicate has a redox‐driven reversible change in chiroptical properties.
