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 achiral counterpart is demonstrated.
