(A) UV-vis absorption spectra of different concentrations of (γ-CyD)2/C60 and (B) C60(OH)24 in aqueous solution. Spectra from bottom to top correspond to [(γ-CyD)2/C60] or [C60(OH)24] = 0.1, 0.3, 0.5, 0.7, 1, 2, 4, 6, 8, 10, 15, 20, 30, 40, and 50 μM. Inset: Plot of the peak absorbance against the concentration; path length, 1 cm. (C) Structure of (γ-CyD)2/C60. (D) Possible structure of C60(OH)24 aggregates in aqueous solution.
