The microstructural features of the LB films of C60 have been studied by using high resolution electron microscopy. In the ordered regions of the films, lattice fringes of C60 were observed. The selected area electron diffraction patterns possess hexagonal symmetry and can be indexed as a hexagonal unit cell with parameter a = 1.0 nm. Defects, dislocations and even more disordered arrangements of C60 can also be observed in the different regions of the films. However, the most parts of the films exist in the amorphous state.
