Abstract

The cover illustrates self-assembly of a hexa-peri-hexabenzocoronene amphiphile to give a graphitic nanotube, formed through helical rolling-up of a bilayer tape consisting of bilaterally coupled columns of π-stacked hexabenzocoronene units. The graphitic layer inside the wall offers a charge-transport pathway. Aida and co-workers report on p. 1297 on the fabrication of a macroscopic fiber by “fishing” the nanotubes with a glass hook. In the fiber, most of the nanotubes are oriented unidirectionally along the fiber axis, thereby allowing an anisotropic electrical conduction upon doping with iodine.
