Intense current interest in supramolecular chemistry is devoted to the construction of molecular assemblies displaying controlled molecular motion associated to recognition. On this ground, molecular ...

Encapsulation of ion pairs in extended, self-assembled structures.

J. Am. Chem. Soc. 134(29) , 11971-3, (2012)

Encapsulation of ion pairs in small spaces that are isolated from the medium is expected to result in amplified interactions between the ions. Yet, sequestration of ion pairs in self-assembled capsule...

New supramolecular organization for a glycoluril: chiral hydrogen-bonded ribbons.

Chem. Commun. (Camb.) (19) , 2228-9, (2002)

A series of substituted glycoluril molecules exhibits a substantial twist of the fused five-membered rings and assembles exclusively chiral hydrogen-bonded ribbons in the solid-state.
