Abstract

We found by means of transmission electron microscopy and atomic force microscopy that the empty SWNTs and C 70 -peapods form helical nanostructures in the shapes of rings, irregular rings, lassos, handcuffs, catenanes, pseudo rotaxanes and figure 8 structures. The mechanism of the superstructure formation has been discussed in relation to the unique characteristics of stiff polymer chains with the aid of an off-lattice Monte Carlo simulation.
