Metal-mediated self-assembly is emerging as a very important strategy for the synthesis of
supramolecular species. Still, a major challenge in coordination supramolecular chemistry …

Metal directed self-assembly has yielded a wide array of two-and three-dimensional
structures with fascinating new chemical properties. These structures have typically been …

A neutral 2-site chloride selective compound has been developed (3), based on a 1, 3-
alternate tetrasubstituted calix [4] arene providing a preorganized supramolecular scaffold …

Self-assembly—the spontaneous generation of order in systems of components—is
ubiquitous in chemistry; in biology, it generates much of the functionality of the living cell …

Strategies for the design of ligands that combine with metal ions to form high-symmetry
coordination assemblies are reviewed. Evaluation of crystal structure evidence reveals that …

An excellent overview of the manifold aspects of modern crystal engineering. From design
and preparation to spectroscopy and applications, this handbook both covers and evaluates …

Tripodal tris (urea) cationic receptors 1 and 2 containing p-tolyl or octyl substituents,
