    摘要: The present invention provides methods of preparing functionalized graphene nanoribbons. Such methods include: (1) exposing a plurality of carbon nanotubes (CNTs) to an alkali metal source in the presence of an aprotic solvent to open them; and (2) exposing the opened CNTs to an electrophile to form functionalized graphene nanoribbons (GNRs). The methods may also include a step of exposing the opened CNTs to a protic solvent to quench any reactive species on them. Additional methods include preparing unfunctionalized GNRs by: (1) exposing a plurality of CNTs to an alkali metal source in the presence of an aprotic solvent to open them; and (2) exposing the opened CNTs to a protic solvent to form unfunctionalized GNRs.

    摘要: Various embodiments of the present disclosure pertain to methods of making magnetic carbon nanoribbons. Such methods generally include: (1) forming carbon nanoribbons by splitting carbon nanomaterials; and (2) associating graphene nanoribbons with magnetic materials, precursors of magnetic materials, or combinations thereof. Further embodiments of the present disclosure also include a step of reducing the precursors of magnetic materials to magnetic materials. In various embodiments, the associating occurs before, during or after the splitting of the carbon nanomaterials. In some embodiments, the methods of the present disclosure further comprise a step of (3) functionalizing the carbon nanoribbons with functionalizing agents. In more specific embodiments, the functionalizing occurs in situ during the splitting of carbon nanomaterials. In further embodiments, the carbon nanoribbons are edge-functionalized. Additional embodiments of the present disclosure pertain to magnetic carbon nanoribbon compositions that were formed in accordance with the methods of the present disclosure.
