ResumoThis review article describes graphitic nanotubular objects formed by programmed self-assembly of Gemini-shaped hexa-peri-hexabenzocoronene (HBC) derivatives. The nanotubes are characterized by an aspect ratio greater than 1000 and have a uniform diameter of 20 nm, which is an order of magnitude larger than those of carbon nanotubes. The wall of the nanotubes consists of a helical array of the π-stacked graphene molecules. The inner and outer surfaces of the nanotubes are covered by hydrophilic triethylene glycol chains. Upon oxidation, the graphitic nanotubes become electroconductive. Modifications of the chemically accessible surface result in the formation of nanotubes with various properties.
