Molecular braids: Quintuple helical hydrogen bonded molecular network

The synthesis of 1, characterized by a calix[4]arene backbone in 1,3- alternate conformation bearing four pyridines acting as hydrogen bond acceptors, was achieved and its solid state structure studied by X-ray diffraction on a single crystal; in the presence of 4,4'-biphenol 6 acting as a dihydrogen bond donor, compound 1 formed infinite single strand helical 1-D molecular networks which upon lateral association were packed in the crystalline phase as quintuple helices.

Inclusion complexes of a new family of non-ionic amphiphilic dendrocalix[4]arene and poorly water-soluble drugs naproxen and ibuprofen

The inclusion complexes of a new family of nonionic amphiphilic calix[4]arenes with the anti-inflammatory hydrophobic drugs naproxen (NAP) and ibuprofen (IBP) were investigated. The effects of the alkyl chain's length and the inner core of calix[4]arenes on the interaction of the two drugs with the calix[4]arenes were explored. The inclusion complexes of Amphiphiles 1a-c with NAP and IBP increased the solubility of these drugs in aqueous media. The interaction of 1a-c with the drugs in aqueous media was investigated through fluorescence, molecular modeling, and 1H-NMR analysis. TEM studies further supported the formation of inclusion complexes. The length of lipophilic alkyl chains and the intrinsic cyclic nature of cailx[4]arene derivatives 1a-c were found to have a significant impact on the solubility of NAP and IBP in pure water.

MATERIALS COATED WITH CALIXARENES

This invention relates to the direct grafting of a calixarene mostly onto the surface of a material, as well as to a grafting process, and certain calixarene intermediates useful for carrying the grafting process.
