B3LYP/6-31G* optimized geometries of an 84 carbon segment derived from Nanotubanol.

The laterally oriented epoxides isomer is more stable than the longitudinally oriented epoxides isomer, by 14 kcal per epoxide.

MMFF Geometries. Most stable conformer has all OH's aligned so H-bonds form a band of 5-membered rings around the tube.

As requested by u/Guess-Competitive.

Fullerenol C60, only $252 per gram from Iris Biotech

(They had a heck of a time trying to add the -OH bonds in back, without overlapping something in front. I think they just gave up.)
