Assignee:

Covalent Partners, LLC - Hayward CA

International Classification:

C07D 291/00

US Classification:

540474, 540460, 540467, 540471, 544238, 544294, 544333

Abstract:

Nanofilms useful for filtration are prepared from oriented amphiphilic molecules and oriented macrocyclic modules. The amphiphilic species may be oriented on an interface or surface. The nanofilm may be prepared by depositing or attaching an oriented layer to a substrate. A nanofilm may also be prepared by coupling the oriented macrocyclic modules to provide a membrane.

International Classification:

C07D 487/00

US Classification:

540471

Abstract:

Certain macrocyclic modules comprising 3-24 synthons are provided herein. Each synthon is independently selected from cyclic substituents, wherein each synthon selected is bonded to the next through a linker to form a closed ring that defines a pore. One or more lipophilic moieties and one or more hydrophilic moieties are bonded to one or more of the synthons, resulting in the formation of the desired macrocyclic modules. Those modules may be subsequently linked to one another to form selectively-permeable membranes. Membranes comprising macrocyclic modules may be useful in filtering certain molecular species from a solution. Selective passage of particular species is determined, in part, by the size of the module's pore and the nature of the lipophilic/hydrophobic species attached thereto. Also provided are methods of making and using macrocyclic modules and membranes.

US Classification:

540/454000, 540/460000, 540/467000, 540/471000

Abstract:

Macrocyclic module compositions are made from cyclic synthons. The macrocyclic module structures are prepared by stepwise or concerted schemes which couple synthons in a closed ring. The macrocyclic module structures may have a pore of nanometer dimensions.
