The formation of one‐dimensional structures of 1,4,11,15,30‐pentakis(biphenyl)‐2‐hydro[60]fullerenes on highly ordered pyrolytic graphite (HOPG) was investigated with an atomic force microscope. These molecules have the shape of a conical shuttlecock with a fullerene at the apex. Topographic images taken in tapping mode showed the formation of round islands, as well as needle shaped structures. The needles arrange in three preferential directions and are only one monolayer high consistent with the formation of molecular chains. Their observed width is compatible with 10 or less molecular rows. By switching into contact mode one can manipulate and disrupt these chains. When switching back into tapping mode, one can observe their regrowth. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
