Ion‐Free and Ion‐Pairing Assemblies of Anion‐Responsive π‐Electronic Systems Possessing Directly Linked Alkyl Chains

Abstract

Alkyl-substituted pyrrole-based anion-responsive π-electronic systems formed supramolecular gels and liquid crystals through effective π-π stacking and van der Waals interactions. The addition of chloride as a planar cation salt afforded ion-pairing assemblies as soft materials comprising planar receptor-Cl(-) complexes and the cation.
