Physicochemical characterization of fullerenol and fullerenol synthesis by-products prepared in alkaline media

Basic hydrolysis of fullerene-based esters: a tiny step away from nucleophilic addition to fullerene

“…tetrabutylammonium hydroxide) used in the synthesis of fullerenols, 26 it is of no practical help when physico-chemical characterization of fullerenol and its by-products is in question. 17 Therefore, such spectra can be used only as an additional support for assumed hydroxylation, rather than an argument against it.…”

“…15 Due to the popularity of fullerenols there still exists a need for improving the synthesis 16 and analytical methods for establishing their characterization. 17 During our recent attempts to further optimize hydrolysis of ethyl ester of T h -FHMA we have observed that under certain conditions a nucleophilic addition of -OH groups to fullerene C 60 cage takes place as a side reaction, leading to the formation of some kind of a hybrid with features of T h -symmetric FHMA and fullerenol (Scheme 1).…”

Controlled deposition of fullerene derivatives within a graphene template by means of a modified Langmuir-Schaefer method

“…Fullerols improve have been proposed for performing bio-oxidations [29,30]. They have been tested as agents for Parkinson's disease (PD) prevention and therapy [31,32], and as active compounds in the preparation of skin rejuvenation cosmetic formulations [33], just to name a few of the many fields of science and technology [34][35][36][37] where C 60 (OH) n have been considered.…”

Fullerol modification ferrihydrite for the degradation of acid red 18 under simulated sunlight irradiation

“…The removal of AR18 by PHF/Fh was reversely related to PHF contents and was lower than that by Fh. PHF was known to have negative charges in the pH range 3.0-9.5 [29], which then might inhibit the adsorption of anionic dyes because of the electrostatic repulsion.…”

“…Wang et al reported that Fh had good photoFenton catalytic performance for the oxidative decomposition of Mordant Yellow 10 under UV irradiation [28]. Fh may have strong interaction with PHF, as PHF generally presents negatively charged surface in the pH range 3.0-9.5 while Fh shows positively charged surface at pH < 8 [29,30]. Moreover, they may form surface composites through the formation of covalent bonds between the surface hydroxyl group on Fh and PHF.…”
