Large organic, custom designed molecules, called HB-HPB (hexa-tert-butyl-hexaphenylbenzene) on Cu(111) are investigated by means of LT-STM. In combination with STM manipulation techniques, the self-ordering properties of the molecules can be exploited to assemble molecules in defined molecular structures. Moreover, the molecules can be utilized to move and aggregate Cu adatoms. This is an example of a single molecular nano-machine, performing the task of an atomic assembler under the operation of the STM tip.
