Catalog No. : PCN-105
Product Name : mPEG-Pyrene, MW 20,000 Da
Description :

PEG-Pyrene is a PEGylated pyrene derivative for the surface functionalization of carbon nanotube (CNT) and graphene, graphene oxide (GO), reduced graphene oxide (rGO), via the strong (close to irreversible) pi-pi stacking between the pyrene and the aromatic rings on single wall and multi-walled carbon nanotubes and other graphitic surfaces. Pyrene is conjugated to PEG through a very stable amide bond. It is a very simple process that requires just dispersing CNT with the PEG-pyrene reagents in either organic solvents or aqueous solutions. The same PEGylated pyrene reagent also works for graphene or any carbon particle surfaces with curvatures that fit well with the pyrene structure. Custom synthesis of functional Pyrene-PEG derivatives is 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.
