The hydrophilic vs. hydrophobic balance for five C60 derivatives (FD1–5) bearing one hydrophilic addend has been evaluated by means of useful descriptors derived from (i) aggregation measurements in aqueous/organic mixtures, (ii) partition measurements between n-octanol and water (log Pm/a), and (iii) retention factors in reverse-phase chromatography (log kw). Aggregates of FD1–5 have been obtained both in water and in aqueous organic mixtures. The dimension of the aggregates has been estimated by gel-permeation chromatography.

Abstract
The hydrophilic vs. hydrophobic balance for five C60 derivatives (FD1–5) bearing one hydrophilic addend has been evaluated by means of useful descriptors derived from (i) aggregation measurements in aqueous/organic mixtures, (ii) partition measurements between n-octanol and water (log Pm/a), and (iii) retention factors in reverse-phase chromatography (log kw). Aggregates of FD1–5 have been obtained both in water and in aqueous organic mixtures. The dimension of the aggregates has been estimated by gel-permeation chromatography.
