The two-volume Encyclopedia of Supramolecular Chemistry offers authoritative, centralized
information on a rapidly expanding interdisciplinary field. User-friendly and high-quality …

Urea, which has both hydrogen bond acceptor and donor moieties, is an ideal structure for a
supramolecular synthon. Various supramolecules having ureido group (s) have been widely …

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 …

A new tripodal receptor for the recognition of monosaccharides is described. The
prototypical host 1 features a 1, 3, 5-substituted 2, 4, 6-triethylbenzene scaffold bearing three …

Calix [4] pyrroles having extended aromatic cavities have been functionalized with 4 ureas
in the para position of their meso phenyl substituents. This elaboration of the upper rim was …
