Noncovalent Functionalization of Graphene in Suspension
Figure 5
(a) HR-TEM of graphene treated with 2 in toluene. Scale bar corresponds to 5 nm. Arrows and black ovals indicates some of the large number of [60]fullerene candidates distributed over the surface, all of which appear brighter than the background. The contrast was enhanced digitally. (b) Cartoon depicting 2 on a graphene surface, consistent with the observations of the [60]fullerene-graphene and [60]fullerene-pyrene-graphene systems.
