| Popis: | The water‐soluble fullerene C60 oxygen and hydroxyl group derivatives were prepared by means of C60 water solution visible light illumination and C60 toluene solution by ozonolysis. The experimental investigation was carried out by UV‐Vis, IR, Raman spectroscopy, XPS, and AFM. The structure C60 derivatives in water solution (single molecules and its aggregates with hydrated shell, nanocrystals), chemical composition and electronic structure of C60 derivatives containing both hydroxyl groups and >C˭O were studied. A comparison of these spectra for C60 derivatives water solution with the data for their adsorbed layers allowed to detection a series of oxidation products. This data for the C60 derivatives is the basis of development of efficient photosensitizers. |
