Supramolecular Chemistry: C. Schmuck* pp. 5830 – 5833: Guest Encapsulation within Self-Assembled Molecular Containers
Abstact: Molecular hospitality: Self-assembled molecular containers provide a very specific geometric as well as chemical environment for a bound guest,which allows for selective guest binding or the stabilization of unstable molecules or unstable conformations within the capsule. The geometric constraints imposed by the container can even change the outcome of a chemical reaction.

Abstract: Torsional strain has been used to control the pitch of helical nanostructures in the range of tens to hundreds of nanometers. In this method, sterically induced torsional strain on the primary helices forces the secondary helices into superhelices,with the pitch tunable depending on the magnitude of the strain. UV radiation can be used to switch the pitch of specific helical nanostructures.
