Optimized solvent-exchange synthesis method for C60 colloidal dispersions

Optimization of the solvent-exchange process for high-yield synthesis of aqueous fullerene dispersions

“…Derivatization and solubilization have been disregarded in this field. The most relevant techniques of AFD preparation are solvent exchange [11,14,15], dialysis [16], and mixing [17][18][19]. However, the total yield of fullerene transfer into water of 100 % has not yet been achieved, which leads to significant losses and increases for the cost of the final product, especially for EMFs.…”

“…Apart from the yield, the main drawback for the solvent-exchange process is significant amounts of hazardous organic substances in AFDs [11,14,15]. However, not much attention is paid to the purity of the produced dispersions, which is unacceptable for biomedicine.…”

Self-Assembled Fullerene Nanostructures

“…Various other solvents have been used with or without THF for the production of sub-100 nm low dimensional C 60 nanoclusters. Other examples can be found elsewhere 37,38 . Recently Park et al 39 investigated the critical effect of solvent geometry on the morphology of C 60 prepared by a drop-drying process at room temperature.…”

Contaminant‐mobilizing capability of fullerene nanoparticles (nC60): Effect of solvent‐exchange process in nC60 formation

“…Several literature reports indicate that when a solvent-exchange method is used to prepare nC 60 , the type of solvent used during the preparation could affect the size, stability, and surface chemistry of nC 60 [8,22,23]. We hypothesize that the types of solvents and the detailed routes involved in the preparation of nC 60 may have even greater effects on the aggregation and thus pore structures of nC 60 and that this subsequently affects nC 60 -contaminant interactions.…”
