The study hinted that the presence of at least one double bond is required in the lipophilic side chain to form twisted nanostructures and impart supramolecular chirality. Studies on the formation of helical nanostructures are limited to the presence of chiral carbon centers and have been well established by Furhop et al. [73]. Various hydrophilic chiral moieties such as glucose, galactose, open-chain...

Supramolecular chirality can be introduced in columns of discotic molecules by using specific interactions, apart from the arene-arene interactions. To achieve this, a study with chiral dopants has been performed.73 Hexa-n-hexyloxytriphenylenes were mixed in dodecane solutions with a variety of chiral electron-deficient dopants and the resulting charge transfer complexes... 

Compound 72 was shown to display enantioselectivity in the extraction of chiral potassium salts from water into the organic phase.105 The supramolec-ular polymer possesses a homochiral helical architecture onto which one of the anionic enantiomers preferentially binds. Intriguingly, for some of the anions the octamer and polymer showed opposite selectivity, illustrating the difference in supramolecular chirality of the two systems. Furthermore, the polymer was capable of inducing a Cotton effect in the achiral compound potassium A-(2,4-dinitrophenyl)glycinate. Since the apolar side chains would... 

The growing interest in supramolecular chirality stems not only from the intrinsic relevance of such studies for the origin of chirality in life processes, but also from the potential technological applications, such as the separation of optical isomers for the pharmaceutical or food industries. 

Chirality is expressed on both the molecular and the supramolecular levels. Like a molecule, a supermolecule may exist in enantiomeric or diastereomeric forms. Supramolecular chirality results both from the properties of the components and from the way in which they associate.
