Key words: fullerene, self-assembly, nanostructures, liquid-liquid interfacial precipitation, nanowhiskers, nanotubes, nanosheets 1 INTRODUCTION compose an icosohedra(l Ih)symmetric closed cage struc- Design of nanostructured materials whose properties ture of the C60 molecule(diameter~0.8 nm). In C60, each can be tailored across different length scales so that they carbon atom is bonded to three other carbon atoms can be utilized in different functional systems and nanode- through sp2 hybridized bonds with the tendency for double vices fabrication is a current topic of great interest in the bonds not to be present at the pentagonal rings resulting in field of materials nanoarchitectonics. Self-assembly is one poor electron delocalization, i.e. C60 is not a superaromatic of the special techniques applied for the organization of molecule. As a result, it behaves as an electron deficient functional molecules such as fullerenes, amphiphiles, pro- molecule.
