Abstract
The present invention generally relates to compositions comprising and methods for forming functionalized carbon-based nanostructures.
Claims17
A composition, comprising:
- graphene or graphene oxide comprising at least one functional group associated with the graphene or graphene oxide, wherein the at least one functional group has the structure:
- wherein R1, R2, and R3 are the same or different and each is independently a substituent, optionally substituted;
- and
- G comprises a carbon atom of the graphene or graphene oxide.

A method for fabricating a functionalized carbon-based nanostructure, comprising:
- providing a carbon-based nanostructure comprising a first allylic functional group;
- reacting the carbon-based nanostructure with a reactant comprising at least one carbon atom to transform the first allylic functional group into a second allylic functional group;
- and
- allowing the second allylic functional group to undergo a rearrangement via a sigmatropic rearrangement reaction,
- thereby forming a carbon-carbon bond between the at least one carbon atom within the reactant and a carbon atom within the carbon-based nanostructure,
- wherein the carbon-based nanostructure is graphene or graphene oxide.

A method for fabricating a functionalized carbon-based nanostructure, comprising:
- providing a carbon-based nanostructure including a group having the formula (I):
- wherein C1, C2, and C3 are part of a fused network of aromatic rings within the carbon-based nanostructure and OR5 is a pendant group of the fused network of aromatic rings, and R5 is a substituent, optionally substituted;
- and
- reacting the carbon-based nanostructure with a reactant to produce a group having the formula (II):
- wherein R6, R7, and R8 are the same or different and each is independently a substituent, optionally substituted.
