Covalently linked, water-dispersible, cyclodextrin: reduced-graphene oxide sheets.

摘要: Reduced-graphene oxide (rGO) sheets have been functionalized by covalently linking β-cyclodextrin (β-CD) cavities to the via an amide linkage. The β-CD:rGO sheets, in contrast rGO, are dispersible over a wide range of pH values (2–13). Zeta potential measurements indicate that there is more than one factor responsible for dispersibility. We show here planar aromatic molecules adsorbed on rGO sheet as well nonplanar included tethered β-CD their fluorescence effectively quenched sheets. combine hydrophobicity associated with along cyclodextrin single water-dispersible material.
