The induced supramolecular chirality was found to be dependent on the absolute configuration of lateral residues, that is, the polymers with-configurational oxazolinyl chromophores tended to form chiral aggregates with levorotatory handedness, while polymers obtained from the-monomer offered dextrogyrate one upon the addition of Cu salt. A model, in which side groups would arrange in a helix fashion, is employed for describing the unusual chirality.
