The hydrophilic vs. hydrophobic balance for five C-60 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 (109 P-m/a), and (iii) retention factors in reverse-phase chromatography (log k(w)). 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. © Wiley-VCH Verlag GmbH & Co. KGaA.

Abstract
The hydrophilic vs. hydrophobic balance for five C-60 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 (109 P-m/a), and (iii) retention factors in reverse-phase chromatography (log k(w)). 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. © Wiley-VCH Verlag GmbH & Co.
