Reticular Growth of Graphene Nanoribbon 2D Covalent Organic Frameworks

Synthesis and characterization covalent organic frameworks (COFs) from a small molecule diamine and polydisperse cove type GNRs (c-GNRs) functionalized with aldehydes. The cGNR-COF films were found to contain crystalline regions (>100 nm2) of imine linked GNRs that could be chemically exfoliated into bilayer/trilayers utilizing a sonication protocol with o-dichlorobenzene (o-DCB).
