  • Cyclopropenium polymers and methods for making the same
    Patent number: 10385150
    Abstract: The present invention provides, inter alia, a process for incorporating a cyclopropenium ion into a polymeric system. Processes for making cross-linked polymers, linear polymers, and dendritic polymers, as well as for incorporating a cyclopropenium ion onto a preformed polymer are also provided. Further provided are stable, polycationic compounds, various polymers that contain stable cyclopropenium cations, and substrates containing such polymers. The use of these polymers in water purification systems, antimicrobial coatings, ion-transport membranes, cell supports, drug delivery vehicles, and gene therapeutic vectors are also provided.
    Type: Grant
    Filed: August 14, 2017
    Date of Patent: August 20, 2019
    Assignee: The Trustees of Columbia University in the City of New York
    Inventors: Tristan Hayes Lambert, Luis M. Campos, Jeffrey Bandar, Emma Jane Dell
