| Popis: | The water‐soluble composites with fullerene content up to 5 wt% based on poly‐(N‐vinylpyrrolydone) (PVP) were obtained. The higher fullerene content is achieved by means of introducing tetraphenylporphyrine (TPP) and KBr into composites. The synthesis includes the formation of C60–TPP complex and its further interaction with polymer. The formation of C60–TPP complex was confirmed by 13C NMR, SANS, and translational diffusion. The hydrodynamic and electrooptical studies of C60–TPP–PVP complexes indicate the higher symmetry of the polymer coil in the complex as compared to PVP. The C60–PVP–KBr composites were also obtained by the solid state interaction under vacuum, KBr promoting the destruction of fullerene aggregates. |
