During the past two decades, the self-assembly of organic crystals have been a hot topic widely studied by material chemists.^[1] Among the potential candidate molecules, the spherical fullerene molecules are particularly attracting for their definite structures, high electronic affinity and three-dimensional (3D) electron transporting property.^[2-4] In this presentation, we first systematically investigate the self-assembly behavior of various C₆₀ polyhedron microstructures and also their extraordinarily enhanced luminescence properties. Moreover, C₆₀ well-aligned arrays are readily prepared by a simple dip-coating process, which present excellent UV-photoresponse performances. Furthermore, a solution-processible co-assembly strategy taking advantage of charge-transfer interaction is developed to prepare needle-like fullerene (C₇₀)/cobalt porphyrin supramolecular architectures, which possess excellent electrical conductivity and high thermal resistance. More interestingly, three-dimensional porous carbon structures with abundant functionalities are readily obtained by KOH activation of fullerene (C₇₀) microtubes, exhibiting excellent supercapacitor performances which are much better than that of the original microtubes.^[5]
