Extended surface chirality from supramolecular assemblies of adsorbed chiral molecules
Article Abstract:
It is possible to sustain a single chiral domain across an extended surface, as long as reflection domains of opposite handedness are removed by a rigid and chiral local adsorption geometry. It is also necessary for inequivalent rotation domains to be removed by successful matching of the rotational symmetry of the adsorbed molecule with that of the underlying metal surface. The models proposed in this research have several implications for enantioselective heterogeneous catalysis. It appears that, when simple modifiers are used, the active site is defined by supramolecular assemblies.

Complete asymmetric induction of supramolecular chirality in a hydrogen-bonded assembly
Article Abstract:
Complete enantio-selective self-resolution has been identified in the diastereoselective assembly of enantio-pure calix(4)arene dimelamines and 5,5-diethylbarbituric acid into chiral hydrogen-bonded structures of one handedness. This phenomenon has previously only been seen in hydrogen-bonded assemblies in the solid or liquid-crystalline state. It is also possible to use chiral information in the individual components to control the conformation of the assembly.

Light on chirality
Article Abstract:
Chirality, the non-identity of a molecule with its mirror image, is ubiquitous and chiral photochemistry or photochirogenesis has become an area of rapid growth. Chiral photochemistry, or photochirogenesis essentially requires a physical or chemical source of chirality that can be transferred to the reaction products.
