  • Patent number: 10316432
    Abstract: Provided herein are methods for the manufacture of fibers from solution-phase peptide-based polymers by electrospinning, and compositions produced thereby. In particular embodiments, various embodiments provide electrospinning supramolecular fibers from low concentration peptide amphiphile filaments.
    Type: Grant
    Filed: September 30, 2014
    Date of Patent: June 11, 2019
    Assignee: Northwestern University
    Inventors: Alok S. Tayi, E. Thomas Pashuck, III, Samuel I. Stupp
  • Patent number: 9997272
    Abstract: Organic charge-transfer (CT) co-crystals in a mixed stack system are disclosed, wherein a donor molecule (D) and an acceptor molecule (A) occupy alternating positions (DADADA) along the CT axis. A platform is provided which amplifies the molecular recognition of donors and acceptors and produces co-crystals at ambient conditions, wherein the platform comprises (i) a molecular design of the first constituent (?-complement), (ii) a molecular design of the second compound (?-complement), and (iii) a solvent system that promotes co-crystallization.
    Type: Grant

  • Patent number: 9997271
    Abstract: Organic charge-transfer (CT) co-crystals in a crossed stack system are disclosed. The co-crystals exhibit bidirectional charge transfer interactions where one donor molecule shares electrons with two different acceptors, one acceptor face-to-face and the other edge-to-face. The assembly and charge transfer interaction results in a pleochroic material whereby the optical absorption continuously changes depending on the polarization angle of incident light.
