abstract = {The future success of organic electronic devices strongly
depends on the ability to tailor the properties of thin
films and interfaces. This calls for well-ordered thin
films. However, their properties are dominantly influenced
by the formation of the first molecular layer representing a
template for further growth. The development of the first
layer-in turn-depends on the fine balance of
molecule-substrate and molecule-molecule interaction. The
latter is usually attractive owing to van der Waals forces
and causes the formation of islands and small crystalline
grains. Here, we report on organic adsorbates exhibiting a
repulsive intermolecular interaction. With increasing
coverage, Sn-phthalocyanine molecules continuously rearrange
on Ag(111) in a series of ordered superstructures. They
always fill the surface terraces homogeneously and maximize
the domain size. Thicker films also exhibit extremely large,
monocrystalline grains and potentially enable bulk-like
properties for thin films. The intermolecular interaction
can be tuned by cooling and becomes attractive below similar
to 120 K.},
