摘要：
Fullerenols C-60(OH)(x) with different number of OH- groups ( 3 - 12 per molecule) were obtained by using a specially developed two- step grafting procedure. The regioselectivity of bound to fullerene molecule hydroxyls was proved by solid- state H-1 and C-13 NMR. It has been found that the fullerenols with 2 - 3 OH groups per C-60 contain some amount of non- converted residual t- Bu groups and the solo grafting of one hydroxyl to one bond occurs due to the structure of the intermediate product. Therefore, the fullerenols with a medium number of hydroxyls seem to be the most proper derivatives for further covalent conversions.
