Tubular, needle-like crystals of C60 with diameters ranging from micro to nano sizes have been synthesized by the liquid-liquid interfacial precipitation (LLIP) method. The C60 nano- and microtubes can absorb various solutions of alcohol and water, showing that they can be promising containers for materials storage and recovery. Further, C60 microtubes vertically aligned on porous alumina membranes have been successfully prepared for the first time by a modified LLIP method. The vertically aligned C60 microtubes will find a variety of application for bio and environmental uses.
