                      aromatic π‐orbitals on metal surfaces play an important
                      role for organic electronics and spintronics. Pyrene is a
                      flat aromatic molecule with a size between ultimately small
                      benzene and extended graphene segments. The deposition of
                      pyrene molecules onto clean and reactive surfaces with a
                      sub‐monolayer coverage under ultra‐high vacuum (UHV)
                      conditions is challenging, since pyrene is a solid with a
                      high vapor pressure. Here, a sublimation procedure under UHV
                      and image pyrene adlayers on in situ prepared Au(111) and
                      Fe/W(110) substrates by means of low‐temperature scanning
                      tunneling microscopy is presented. For Au(111), the
                      molecule–surface interaction is weak as indicated by the
                      specific herringbone reconstruction of the Au(111) surface
                      that is visible through the self‐assembled pyrene adlayer.
                      Pyrene desorption due to weak intermolecular interaction
                      self‐limits the growth to one monolayer (ML). On the more
                      reactive 2–4 ML thick Fe films on W(110), the molecular
                      order of the pyrene adlayer sensitively depends on the Fe
                      thickness‐dependent dislocation pattern at the substrate
                      surface. Irregular arrangements occur for 1 ML Fe and near
                      substrate dislocations for 2–4 ML Fe. Self‐assembled
                      ordered arrays form predominantly for 2 ML Fe, where the
                      dislocation pattern leaves sufficiently large unperturbed
                      areas between the dislocation lines.},
