Coordinating the Schiff base of a helicenecdicarbalde‐hyde to nickel centers resulted in the first ladder polymer that has an unbroken network of double bonds winding in one direction along a helix (see the representation on the right). Helicene and nickel salophen units alternate in the product, on average 8.3 times.
