Disclosing chirality in consecutive supramolecular polymerizations: chiral induction by light in N-annulated perylenetetracarboxamides

A multichiroptical characterization of the different aggregates formed by the consecutive supramolecular polymerization of chiral N-annulated perylenetetracarboxamides is reported. They form one-handed helical aggregates, which emit circularly polarized light with remarkable vertical bar g(lum)vertical bar values. In addition, the chiral induction by circularly polarized light in the supramolecular polymerization of the achiral counterpart is demonstrated.
