The cover picture shows that benzene/2,2′‐bipyridine‐alternately incorporated amide polymers are driven by hydrophobicity to form two helical conformations both of which exhibit helicity bias. Switching between the two helical conformations can be tuned by the coordination of the 2,2′‐bipyridine units to Ni2+ ions. More details are discussed in the article by Li et al. on page 678–682.
Two benzene/2,2′‐bipyridine‐alternately incorporated amide polymers have been prepared, which are driven by hydrophobicity to form two different helical conformations. Both helices exhibit twist sense bias in water induced by chiral valine side chains and the coordination of the 2,2′‐bipyridine unit to the Ni2+ ions.
