S. Ravaine et al., SYNTHESIS, PHYSICAL CHARACTERIZATIONS, AND LANGMUIR FILMS OF NEW METHANOFULLERENES, Journal of physical chemistry, 99(23), 1995, pp. 9551-9557
Various methanofullerenes functionalized with either hydrophobic or po
lar groups have been synthesized. Studies of such compounds by surface
pressure measurements and in situ UV-visible spectroscopy in Langmuir
films show that these two types of functionalizations do not prevent
the formation of aggregates at the nitrogen-water interface. Except fo
r one compound studied in the present work, it appears that the aggreg
ation occurs as soon as the spreading of the fullerenes solutions. How
ever, the aggregates obtained appear to have different characteristics
than those obtained with pure C-60.
