Helix versus zig-zag: control of supramolecular topology via carboxylic acid conformations in ortho-substituted phenyl amines.
ortho-Substituted phenyl amines form supramolecular helices or zig-zag structures, depending on the conformation of the carboxylic acid substituents--which can be controlled by an intramolecular hydrogen-bonding interaction.
