Chirally-ordered fullerene assemblies found in organic gel systems of cholesterol-appended [60]fullerenes
Cholesterol-appended [60]fullerene gelators 2a and 2b were prepared and their gelation properties were investigated. 2a with a natural C-3 configuration can gelate dichloromethane whereas 2b with an inverted C-3 configuration could not gelate any solvents. UV/Vis and CD spectroscopic studies indicated that the [60]fullerene moiety in 2a is enforced to chirally orient in the gel state.
