“…NaOH, H 2 SO 4 , and PTC (causes impurities in fullerenol), which is a cleaner approach to produce fullerenol in an easier and a faster way. Previously, C 60 (OH) 12 was used as a starting material to synthesize highly soluble fullerenols [C 60 (OH) 36 , C 60 (OH) 40 ] by vigorously stirring 24 , C 60 (OH) 36 and C 60 (OH) 40 . Moreover, compounds that express specic biochemical functions, which are required for diagnostics as well as drug therapy studies, can be derivatized from C 60 (OH) 8 $2H 2 O by conjugating it with other potential functional groups or biomolecules.…”

A green and clean approach that requires low energy and avoids the use of any toxic or corrosive reagents/ solvents for the synthesis of potential fullerenol moieties [C 60 (OH) n $mH 2 O] was proposed in this investigation, in which pristine fullerene (C 60 ) in dil. H 2 O 2 (30%) aqueous media was ultrasonicated (20 kHz, 200 W) at 30% amplitude for 1 h. The attachment of hydroxyl groups (-OH) was investigated via FTIR and the quantification of -OH groups attached to the C 60 cage was conducted via elemental analysis. The number of secondary bound water molecules (mH 2 O) with each fullerenol molecule [C 60 (OH) n ] was measured via TGA, and the estimated average structure of fullerenol was calculated to be C 60 (OH) 8 $2H 2 O. The synthesized fullerenol was moderately soluble in water and DMSO. Furthermore, the size of the synthesized C 60 (OH) 8 $2H 2 O particles determined by both AFM and DLS analysis was found to be in the range of 135-155 nm. The proposed ultrasound-assisted acoustic cavitation technique encompasses a one-step facile reaction strategy, requires less time for the reaction, and reduces the number of solvents required for the separation and purification of C 60 (OH) 8 $2H 2 O, which could be scalable for the commercial synthesis of fullerenol moieties in the future.

“…Other examples of applications using low-to medium-degree fullerenols have been reported, such as polymer-based solar cells (Cao et al, 2001;Rincón et al, 2005), drug delivery and MRI contrast agents using endohedral metallofullerenol , macromolecular materials and polymer nanocomposites (Goswami et al, 2003;Ouyang et al, 2004), proton conductors (Hinokuma et al, 2001;Maruyama et al, 2002), and electrodeposited films . Following these applications, water-soluble highdegree fullerenols will open the new pathways for the new fullerenol chemistry.…”

“…46 On the other hand, water soluble polyhydroxyl fullerene (fullerenol) was prepared by the modified base method. [47][48][49][50] Under basic condition, the strong electrophilic character of fullerene cage easily releases protons to form fulleroxide anions, (Fol-O) Àn , which is capable of undergoing several types of reactions. Fullerenol undergoes nucleophilic addition reactions on epoxy groups to form star-like macromolecules under mild basic condition.…”

aGraphene is a wonder material possessing unique properties; however, graphene prepared by exfoliation of graphite has property to restack because of van der Waals interactions to form graphite. This restacking can be prevented by insertion of large molecules like fullerene, which not only exfoliates graphite layer but also prevents restacking of prepared graphene sheets. The present article also describes a mild method of graphite oxide synthesis (GO) for lower degree of oxidation resulting in less defected (ruptured carbon framework) graphene sheets. Exfoliation is performed by intercalation of large fullerene molecules by aqueous reaction of fullerene hydroxide (fullerenol) with the epoxy functionalities on graphite oxide to prepare fullerene intercalated graphite (G-Fol). Fullerene functionalization of GO to form G-Fol has been established by FTIR spectroscopy, UV-Vis spectroscopy, TGA and number of layers has been ascertained by Raman spectroscopy, XRD and HRTEM. Stable exfoliation of G-Fol has been confirmed by change in absorbance with time. Photoluminescence property of the material is also evaluated by fluorescence emission and excitation measurement at different excitation and emission wavelengths, respectively. The present article explains a new method of exfoliation of graphite to form stable functionalized graphene layers with fewer defects for future applications as buffer layer in electronic devices.
