  • Soluble graphene nanostructures and assemblies therefrom
    Patent number: 10326077
    Abstract: Disclosed herein is a method for preparing large soluble graphenes. The method comprises attaching one or more hindering groups to the graphene, which can prevent face-to-face graphene stacking by reducing the effects of inter-graphene attraction. The large graphenes can absorb a wide spectrum of light from UV to near infrared, and are useful in photovoltaic devices and sensitizers in nanocrystalline solar cells.
    Type: Grant

    Date of Patent: June 18, 2019
    Assignee: Indiana University Research and Technology Corporation
    Inventors: Liang-shi Li, Xin Yan
