Abstract
The cyclic transformations in shape and crystal structure of C 60 microcrystals in dispersion are experimentally demonstrated by changing the dispersion solvent medium, and keeping the dispersion under ultrasonication. The shape of C 60 microcrystals was changed from as-grown rod-shape to hexagonal disc-shape, then to belt-shape, and again back to rod-shape. The transformation processes were investigated by means of TEM, XRD and FT-IR measurements. As a results, the present transformation is regarded to be a crystal-to-crystal phase transition induced by the exchange of the dispersion medium, which is finally ascribed to weak intermolecular interactions between C 60s inside the crystal.
