Diastereomeric multi-chiral pendant groups: their key role in stimuli-responsive polymeric responses

Abstract

Chiral information transmission in helical polymers bearing multi-chiral pen-dant groups is usually determined by the absolute configuration of the first chi-ral center. The second chiral residue usually has low-to-null influence in themacromolecular handedness of the polymer, due to its remote position respectto the polyene main chain. Here, we demonstrate how the stimuli responsiveproperties of diastereomeric polymers, obtained by changing the absolute con-figuration of the second chiral center, are different due to the unlike propertiesof diastereoisomers
