The C-60 layers on gold were immersed into alkali halides solutions of several concentrations for different time intervals. The results show that C-60 can be removed from the gold surface by iodide when the halide concentration is high and time of immersion is long. A rotated hexagonal structure of iodide is formed on some surface areas although with distortion. Bromide and chloride do not remove C-60 completely from the gold surface. Nevertheless, they are able to penetrate the C-60 layer. The result is that bromide and chloride adsorb on top of the gold and C-60 sits on the halide adlayer. This condition enables the growth of well organized domains of C-60. It is possible to identify the formation of multilayers of the fullerene on some areas. Intramolecular resolution for C-60 was attained in the STM images when the halides were present on the surface. (C) 2013 Elsevier B.V. All rights reserved.
