52_20c/2013Inside Back Cover: Formation of a Homo Double Helix of a Conjugated Polymer with Carboxy Groups and Amplification of the Macromolecular Helicity by Chiral Amines Sandwiched between the Strands (Angew. Chem. Int. Ed. 20/2013)

A π-conjugated polymer with carboxy groups forms a racemic double helix through self-association. However, in the presence of chiral amines, it forms a unique one-handed double helix in which the strands sandwich pairs of chiral amines through cyclic hydrogen-bonding networks. In their Communication on page 5275 ff., E. Yashima et al. report the transferal of chiral information from the amines to the polymer backbone with remarkable amplification of the helical chirality.
