Disclosing chirality in consecutive supramolecular polymerizations: chiral induction by light in -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 | g lum | values. In ad...

Zusammenfassung: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 | g lum | values. In addition, the chiral induction by circularly polarized light in the supramolecular polymerization of the achiral counterpart is demonstrated. A multichiroptical characterization of the light-emitting helical aggregates formed by the supramolecular polymerization of N -annulated perylenetetracarboxamides is reported. The aggregates demonstrate remarkable | g lum | values.
