“…Sulfur trioxide is believed to add successively to C 60 via radical cations to give a polysultonated product. 210 Nitronium ion (NO 2 + ) has been proposed to add to C 60 to give cationic intermediates that can be quenched with water to give fullerenols, 457 but the process could equally well in involve NO 2 • radicals. 458 This work highlights the difficulty of separating redox processes from acid-catalyzed processes (Brønsted or Lewis) in oxidizing superacid media.…”

“…The free fullerene molecule cannot be utilized for many applications because of its hydrophobic nature and limited solubility in most solvents (Chiang, Upasani, & Swirczewski, 1992), thus the chemistry of fullerenes allows the modification of their basic properties in order to be tailored to specific functions because modification causes the molecule to be more reactive and versatile for several applications (Maggini, Scorrano, & Prato, 1993).…”

Fullerenes were initially found to be inert, but their unique cage structure and solubility in organic solvents opened up their susceptibility to functionalization via addition and redox reactions. Endohedral and exohedral derivatives of Buckminster fullerene [C 60 ] have created a niche in the application of carbon nanomaterials in the medical, electronics, energy and water treatment/conservation sectors.

The temperature of water-ice crystallization initiation decreases (∆T) were determined in the binary water solutions of water soluble derivative of light fullerene C 70 with amino-acid lysine at 272.99 -273.15 K. Partial molar excess functions for H 2 O were calculated. For the thermodynamic description of our systems, we have elaborated an original semi-empirical model VD-AS (Virial Decomposition Asymmetric Model), based on the virial decomposition of the molar Gibbs energy of the component molar fractions in the solution. With the help of the VD-AS model, partial molar functions of nano-clusters were calculated. Excess and full average Gibbs energies for the solutions and miscibility gaps concentration regions (with the help of diffusional instability equations) were calculated. Thus, the VD-AS model excellently describes pre-delamination or micro-heterogeneous-structure formation in the considered solutions. These calculations were accordingly confirmed by dynamic light scattering data.
