Supramolecular Polymers: Flexible Chirality in Self‐Assembled N‐Annulated Perylenedicarboxamides (Small 20/2017)

Chirality constitutes a source of inspiration for scientists. The oscillating helicity detected for the supramolecular polymers formed by the self-assembly of three N-annulated perylenedicarboxamides is described in article number 1603880, by Enrique Ortí, and Luis Sánchez, and co-workers. The cooperative supramolecular polymerization of these compounds generates helical, chiral supramolecular structures, which bundle into nanofibrillar structures to afford a highly anisotropic environment. The flexible circular dichroism behavior shown by these self-assembling units can be utilized for the spectroscopic visualization of the torsional flows generated in a vortex.
