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]
