Green and rapid preparation of long-term stable aqueous dispersions of fullerenes and endohedral fullerenes: The pros and cons of an ultrasonic probe
A green, scalable, and sustainable approach to prepare aqueous fullerene dispersions (AFD) C(60), C(70), endohedral metallofullerene Gd@C(82), and their derivatives C(60)Cl(6), C(70)Cl(10), and supramolecular and ester-like derivatives, 10 fullerene species total, is proposed. For the first time, an...

description | A green, scalable, and sustainable approach to prepare aqueous fullerene dispersions (AFD) C(60), C(70), endohedral metallofullerene Gd@C(82), and their derivatives C(60)Cl(6), C(70)Cl(10), and supramolecular and ester-like derivatives, 10 fullerene species total, is proposed. For the first time, an immersed ultrasonic probe was used to preparing dispersions for pristine fullerenes without addends. Both ultrasound-assisted solvent-exchange and direct sonication techniques for AFD preparation using an immersed probe were tested. The average time for AFD preparation decreases 10–15 times compared to an ultrasound-bath-assisted technique, while final fullerene concentrations in AFDs remained at tens of ppm (up to 80 ppm). The aqueous dispersions showed long-term stability, a negatively charged surface with a zeta potential up to –32 mV with an average nanocluster diameter of no more than 180 nm. The total anionic and cationic compositions of samples were found by inductively coupled plasma atomic emission spectroscopy and chromatographic techniques. The highlights and challenges of using an ultrasound probe for AFD production are discussed. |
