Oriented Salts: Dimension‐Controlled Charge‐by‐Charge Assemblies from Planar Receptor–Anion Complexes

Abstract

Pillars of salts: By combining planar cations and planar anionic structures based on π-conjugated acyclic dipyrroles containing an anion, charge-by-charge assemblies could be formed (see picture). Not only crystals but also soft materials, such as supramolecular gels and thermotropic liquid crystals, could be made by this method.
