摘要：

We report the preparation of hierarchically structured fullerene C-70 cubes (HFC) composed of mesoporous C-70 nanorods with crystalline pore walls. Highly crystalline cubic shape C-70 crystals (FC) were grown at a liquid liquid interface formed between tert-butyl alcohol and C-70 solution in mesitylene. HFCs were then prepared by washing with isopropanol of the FC at 25 degrees C. The growth directions and diameters of C-70 nanorods could be controlled by varying washing conditions. HFCs perform as an excellent sensing system for vapor-phase aromatic solvents due to their easy diffusion through the mesoporous architecture and strong pi-pi interactions with the sp(2) carbon-rich pore walls. Moreover, HFCs offer an enhanced electrochemically active surface area resulting in an energy storage capacity 1 order of magnitude greater than pristine C-70 and fullerene C-70 cubes not containing mesoporous nanorods.
