Fabrication of dimension-controllable nano/mesoscopic architectures is an important challenge in nanoscience and nanotechnology, since it can exploit the advantageous intrinsic optoelectronic properties of π-conjugated systems in their molecular building blocks. Supramolecular method that is being utilized in my research is controlling the architecture and dimensionality of hierarchical fullerene (C₆₀) nanostructures by varying the nature of the solvent system, this approach induces “Fullerene Polymorphism”. Flower-like fractal superstructures are obtained in the study and they show superhydrophobic property at the surface. Other focus is development of new fluid nanocarbons such as semi-conducting liquid crystalline-C₆₀ and room temperature liquid-C₆₀. The liquid-C₆₀ is a single component nanocarbon material with high fluidity and shows the potential use in practical materials. A delicate balance of the intermolecular interactions leads to a wide variety of supramolecular morphology and this understanding of the hierarchical assembled systems should inspire further studies for self-organized supramolecular chemistry, nanocarbon science, bio-mimetic structures, nanotechnology as well as materials science.
