Patents by Inventor Alexander K. Shveyd

Alexander K. Shveyd has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
    Type: Grant
    Filed: August 30, 2016
    Date of Patent: June 12, 2018
    Assignee: Northwestern University
    Inventors: Samuel I. Stupp, J. Fraser Stoddart, Alexander K. Shveyd, Alok S. Tayi, Chi-Hau Sue, Ashwin Narayanan
  • 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.
