Fullerene hierarchical mesocrystals were first prepared by antisolvent induced precipitation method. Their morphologies and sizes can be controlled by adjusting the antisolvent type and the ratio between the solvent (toluene) and antisolvent (ethyl acetate or tetrahydrofuran). The formation of fullerene mesocrystals and their transformation to single crystal were observed by time-dependent experiments with SEM and TEM. Fullerene mesocrystals can be separated from the solution and are stable for several months. HRTEM revealed that mesocrystals were made up of highly oriented nanoparticles. The formation of fullerene mesocrystals and their transformation to single crystals provide a new way for the construction of fullerene nanostructures with different applications.
