Noncovalent Functionalization of Graphene in Suspension

Figure 3

(a) Fluorescence titration (𝜆_exc=344 nm) adding 100/200/300 μL of a 0.2 mg/mL graphene suspension in toluene to a solution of 1 in toluene, [𝟏]_initial≈6.26×10⁻⁶ mol/L. (b) Normalized titration data at two fluorescence wavelengths. Intensity of (1 + volume of graphene or MWCNT suspension)/Intensity of (1 + volume of solvent).
