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 |glum| values. In addition, the chiral induction by circularly polarized light in the supramolecular polymerization of the achiral counterpart is demonstrated.
