Patent number: 8110679Abstract: 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.Type: GrantFiled: July 31, 2008Date of Patent: February 7, 2012Assignee: Covalent Partners LLCInventors: Joshua W. Kriesel, Timothy B. Karpishin, Donald B. Bivin, Grant Merrill, Martin S. Edelstein, Thomas H. Smith, Jeffery A. Whiteford, Robert T. Jonas, Mark Micklatcher, Serena Joshi

Patent number: 7767810Abstract: 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.Type: GrantFiled: August 8, 2005Date of Patent: August 3, 2010Assignee: Covalent Partners, LLCInventors: Joshua W.

Patent number: 7595368Abstract: Nanoflims useful for filtration are prepared from amphiphilic species and one or more polymeric components. The amphiphilic species or components may be oriented on an interface or surface. A nanofilm may be prepared by coupling one or more of the components. The nanofilm may also be deposited or attached to a substrate.Type: GrantFiled: August 10, 2005Date of Patent: September 29, 2009Assignee: Covalent Partners, LLCInventors: Joshua W. Kriesel, Donald B. Bivin, David J. Olson, Jeremy J. Harris

Patent number: 7563890Abstract: Certain amphiphilic modules comprising 3-24 synthons are provided herein. Each synthon is independently selected from aryl, heteroaryl, alicyclic, and heteroalicyclic substituents, wherein each synthon selected is bonded to the next through a linker to form a closed ring that defines a nanopore. 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 amphiphilic modules. Those modules may be subsequently linked to one another to form two-dimensional close-packed planar arrays, referred to as nanomembranes. Nanomembranes may be useful in filtering certain ionic species from a solution. Selective passage of particular species is determined, in part, by the size of the module's nanopore and the nature of the lipophilic/hydrophobic species attached thereto. Also provided are methods of making and using amphiphilic modules and nanomembranes.Type: GrantFiled: August 18, 2005Date of Patent: July 21, 2009Assignee: Covalent Partners, LLCInventors: Timothy B. Karpishin, Josh Kriesel, Grant Merrill, Donald B. Bivin, Thomas H. Smith, Martin Stuart Edelstein
