Morphologies of C60 deposited on a substrate

Graphene mediated self-assembly of fullerene nanorods

“…This can be attributed to the choice of CVD grown graphene on copper as the substrate along with the choice of toluene as the solvent, both of which combine to promote the formation of stable aggregates that serve as nuclei, enabling the growth of FNRs, when subjected to the directed air-stream. Further the DAS-FNRs are characterized by their ability to be polymerized during self-assembly, in contrast to the SD-structures as well as structures obtained in the studies of Yao et al, 23 Wang et al, 10 Sallgren et al, 24 and Tiwari et al, 4 which were not susceptible to polymerization.…”

“…[1][2][3]11,20 In LLIP, a mixture of two solvents, one in which C 60 molecules are soluble, is used for forming fullerene nanostructures. In addition to LLIP, which is often a time-consuming process, slow evaporation of solvents containing dissolved fullerenes on substrates, 10,23,24 as well as more complex and expensive methods have been developed for fabricating fullerene based assemblies; these include encapsulation within amphiphilic hexagonal porphyrin matrix, 21 controlled alignment of nanorods via cross-linking 22 and templated 'drip-and-dry' techniques. 25 As an alternative to these methods, we present a simple, straightforward and rapid process that relies on selfassembly for synthesizing faceted FNR, mediated by graphenebased substrates.…”

“…Further, the time-scale of self-assembly corresponded to a few hours. Sallgren et al, 24 were able to obtain a distribution of microcrystals and cylindrical needles and rods, by evaporating C 60 in benzene solutions on copper, while Tiwari et al, 4 using toluene, synthesized rod-like crystals on molybdenum. In the latter two cases, information on the time-scale of the selfassembly process is not available.…”

Enantioselective Surface Plasmon Resonance Sensor Based on C60 Fullerene‐Glutathione Self‐Assembled Monolayer (SAM)

“…Since then, numerous adsorbate/substance combinations have been found to form self‐assembled monolayers (SAMs). On the other hand, films of fullerenes have been prepared using different strategies, including gas‐phase deposition, Langmuir‐Blodgett, and self assembly techniques. To our knowledge, SAM based on fullerene was not used until now for enantioanalysis.…”
