Cover Picture: Aromatic Amide Polymers that Form Two Helical Conformations with Twist Sense Bias in Water (Chin. J. Chem. 7/2016)
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.
