Abstract:Novel monocyclic macrocyclic compounds having nitrogen bridgehead atoms and having in the hydrocarbon bridging chains at least two additional hetero atoms selected from the group consisting of sulfur, oxygen, and nitrogen, when admixed with a compatible cation-donor compound form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing agent. The novel macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.

Abstract:Novel polycyclic macrocyclic compounds having four tertiary nitrogen bridgehead atoms and six bridging chains, each of which have not more than twelve directly connecting atoms between each pair of bridgehead nitrogens, said bridging chains being hydrocarbon chains and hetero-substituted hydrocarbon chains having at least one hetero connecting atom selected from the group consisting of oxygen, sulfur, and nitrogen, at least two of said chains being hetero substituted. When admixed with a compatible cation-donor compound, the polycyclic macrocyclic compounds form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing acid. The novel polycyclic macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.
The polycyclic macrocyclic compounds are prepared by condensation reactions utilizing high dilution techniques, e.g. by condensing a monocyclic macrocyclic having secondary nitrogen bridgeheads with a substituted hydrocarbon di-carbonyl halide followed by reduction of the resulting lactam or, alternatively, by condensing a monocyclic macrocyclic having secondary nitrogen bridgeheads with a substituted hydrocarbon dihalide (or di-sulfonate).

Title:Dynamers: polymeric materials exhibiting reversible formation and component exchange
Publication Type:United States Utility Patent
Publication Date:Jan 8, 2004
Filing Date:Jun 24, 2003
Inventors:Lehn Jean-Marie, Skine W G
Assignee:Lehn Jean-Marie, Skene W G
Abstract:Alternating co-polymers involving the polycondensation of dihydrazides or diamines with dialdehydes reversibly exchange either one or both of their fundamental repeating monomer units in the presence of different monomer units. Furthermore, upon exchange of one of the repeating monomer units, the original monomer unit displaced can be re-introduced into the polymer, or the remaining unexchanged original monomer unit may also be interchanged. The polymers subjected to monomer exchange/interchange exhibit vastly different physical properties than those of the original unexchanged polymer. These dynamic, reversible polymers are therefore able to incorporate, decorporate or reshuffle their constituting monomers, in particular, with respect to environmental physical or chemical factors (heat, light, chemical entities, etc.). They thus have combinatorial features and represent adaptive materials.
