Carbon 60 Hydrated Fullerenes does not contain any hydroxyl groups.
You keep saying that, but the slide presentation you linked to clearly shows six OH groups in the innermost shell.
You got your chemistry WRONG turnbuckle—The (OH) you are referring to is a OH(-) anion of water and not a covalently attached hydroxyl group/tail.

Translated reply from Dr. Grigoriy Andrievsky
First of all, C60HyFn not a polyhydroxyl analogue of the chemical derivatives of C60 – such as fullerenols (C60 {OH} n) -, where the OH- group is covalently "attached " to the surface of carbon in C60.
According slides 59,69,69 and especially to slides 48-52 in the aquatic environment, near the surface of C60 molecules there is an increase / enhancement of the hydrolysis of water molecules that are thousands of times lighter compared to the dissociation of water in bulk. There the "OH" refers to
conventional OH (-) anions, which is a consequence of water dissociation reaction specifically:
H2O <-> H (+) + HO (-) with pK = 7, but for C60HyFn - pK = 3.5 !!!

Він далі каже:,
After a first pass through the file, I noted where I got the idea there were six OH groups involved in hydrated C60--slides 59, 64 & 65, for instance, show OH groups.
=================================
Поперше, C60HyFn не є аналогом полігидроксильованих хімічни похідних С60 - fullerenols (C60{OH}n) -, у яких OH- групи є ковалентно "прив'язанними" до углецевої поверхні С60.
У відповідності слайдам 59,69,69, а особливо до слайдів 48-52, в водному середовищі, поблизу поверхні молекули С60 вібувається підвищенний/посиленний гідроліз молекул води, який в тисячі разів є полегшеним в порівнянні з дисоціацією води in bulk. Там "OH" є звичайними OH(-) anions, які є слідством звістної реакції дисоціації води:
H2O <--> H(+) + HO(-) з pK=7,
but for C60HyFn - pK= 3.5!!! (G.V. Andrievsky, V.K. Klochkov, A. Bordyuh, G.I. Dovbeshko. COMPARATIVE ANALYSIS OF TWO AQUEOUS-COLLOIDAL SOLUTIONS OF C60 FULLERENE WITH HELP OF FT-IR REFLECTANCE AND UV-VIS SPECTROSCOPY. Chem. Phys. Letters, 364 (2002) 8-17).
