Abstract

Star-shape derivatives of C60 with poly(N-vinylpyrrolidone) chains, grafted to C60, were studied in aqueous solution by small-angle neutron scattering in the range of q = 0.04-0.8 nm-1 and dynamic light scattering. From SANS data we found the functionality of fullerene center n≈4. Really a star's gyration radius ∼6 nm exceeded the Gaussian molecular size by ∼40% and the volume was increased by the factor of 3. Such polymer shells make stars' interaction stronger leading to their association. Dynamic light scattering indicates the formation of extended associates (∼ 1000 nm in diameter) involving ∼ 10% of stars.
