MAC it happen : Presented is a study of the synergistic structuredirecting effect of metal–amine complexes (MACs) with different chelating polyamine ligands and imidazolium-based ionic liquid (IL) cations. For the first time, a layered selenidostannate with an asymmetric eight-membered ring, an organic-decorated layered selenidostannate, and a 3D selenidostannate with both the MAC and IL cation...

Chirality Selection in Crystallization

A cluster growth model is proposed to study chiral symmetry breaking in stirred crystallization from an achiral element. Achiral monomers are assumed to coagulate to form chiral clusters from dimers to hexamers. Due to the stirring, the hexamers break into dimers. The coagulation of two dimers into a tetramer also occurs. The fixed point analysis of coupled rate equations of cluster densities a...

Asymmetric Reaction Using Molecular Chirality Controlled by Spontaneous Crystallization

Imposition of chirality in a dinuclear triple-stranded helicate by ion pair formation.

Chirality is a fundamental property intrinsic to many supramolecular systems.2 Helical assemblies are inherently chiral, regardless of the stereotopic information contained within the individual building blocks.3-5 Metallo-supramolecular helicates, assembled from achiral ligands and metal centers, form racemic mixtures of clockwise and counterclockwise structures in which all the metal centers ...
