Résumé :

Tetrabromocavitand bowls are converted into rim-connected hexabromodimers in one step in 17–22% yields by oxidative coupling of higher order arylcuprates. 1H NMR and single crystal X-ray analyses of the rim-connected dimers reveal a conformationally restricted structure in which the rims of the two cavitand bowls describe planes angled at 78.8° to one another. Each of the two bowl cavities are occupied by a guest, in addition to being partially occluded by a portion of the complementary bowl rim. These new host compounds exhibit a very unusual form of enantioisomerism.

Résumé :

Supramolecular chemistry involves non-covalent interactions and specific molecular recognition of molecules/analytes by host molecules or supramolecules. These events are present in synthesis, catalysis, chiral separations, design of sensors, cell signaling processes and drug transport by carriers. The typical behavior of supramolecules is derived from their ability to build well-structured self-assembled and self-organized entities. Cavitands are a particular group of supramolecules possessing a cavity able to include a variety of compounds thanks to host-guest non-covalent interactions devel

Résumé :

Cavitand- Zn porphyrin conjugates self-assemble to give supramolecular (1 + 1) structures upon coordination of bifunctional ligands such as 4,4'-bipyridine and the like. The formation of the capsule depends on key structural factors, such as the size of the cavity, and the possibility of the onset of hydrogen bonds, π–π and π–cation interactions. The extension of this protocol to chiral bifunctional ligands, such as (+)-cinchonine and (−)-cinchonidine, and cinchona alkaloid derivatives, results in the achievement of supramolecular structures with chiral cavities, whose configuration is depende
