Supramolecular Chirality in Artificial Systems

The first approach (Fig. 4A) called diastereoselective non-covalent synthesis regards the self-assembly of chiral units which bear stereogenic centers or which are intrinsically chiral (for instance because of atropoiso- 

Entrapment of guests within self-assembled capsules provides a fourth method for the construction of chiral supramolecular aggregates. In fact, confinement of guests into cavities with a proper shape and size limits their available space and allows the control over their reciprocal positioning. This reflects directly into their mutual electronic and steric interaction and, as a consequence, in their stereorecognition (Fig. 4D).
