Unique macromolecules that fold into a preferred-handed helical conformation induced by chiral substituents covalently bonded to the polymer main-chains as the pendant groups or external chiral stimuli followed by memory of the helical chirality are mainly presented. Chirality sensing in solution by means of circular dichroism (CD) (1 �3 ), chiral separation of enantiomers by chromatography (4 �7 ), and enantioselective asymmetric catalysis (4 , 7 ) based on the helical polymers are also described.1,2 References1) E.
