PEG Reagents for Surface Functionalization of Carbon Nanotubes and Graphenes
PEGylated pyrene derivatives can be used for the surface functionalization of carbon nanotubes and graphenes via the strong (close to irreversible) pi-pi stacking between the pyrene and the aromatic rings on single wall and multi-walled carbon nanotubes.
How Surface Functionalization Works
Pyrene is conjugated to PEG through a very stable amide bond. It is a very simple process that requires just well dispersing CNTs with the PEG-pyrene reagents in either organic solvents or aqueous solutions. The same PEGylated pyrene reagent also works for graphene or any carbon nanoparticle or microparticle surfaces with curvatures that fit well with the pyrene structure.
Functional Pyrene-PEG derivatives are also offered including but not limited to: Pyrene-PEG-Pyrene, Amine-PEG-Pyrene, Acrylate-PEG-Pyrene, Biotin-PEG-Pyrene, FITC-PEG-Pyrene, Rhodamine-PEG-Pyrene, Maleimide-PEG-Pyrene etc.
