      abstract     = {A thus far unknown phase of
                      1,4,5,8-naphthalene-tetracarboxylic dianhydride (NTCDA) on
                      Ag(111), characterized by an all perpendicular orientation
                      of the planar molecules and bound to the Ag substrate
                      through the carboxyl oxygen atoms has been identified using
                      infrared absorption spectroscopy and scanning tunneling
                      microscopy. Its formation process requires second layer
                      NTCDA to squeeze into empty spaces between relaxed monolayer
                      NTCDA molecules. Remarkably, this process causes initially
                      parallel oriented NTCDA to likewise adopt the new, highly
                      inclined adsorption geometry. According to our SPA-LEED and
                      STM findings, the new phase displays a distinct long range
                      order and shows a pronounced tendency to form 1D rows or
                      narrow islands. We suggest that extra NTCDA preferentially
                      transforms into the upright configuration close to existing
                      islands and attaches to them, i.e. the transformation
                      process proceeds in a directed and recurrent manner (reverse
                      domino scenario). Identical processing starting with a
                      compressed NTCDA/Ag(111) monolayer leads to a purely
                      parallel oriented bilayer, that is, the NTCDA monolayer
                      phase is retained and merely acts as a passive template for
                      bilayer NTCDA. The new vertical NTCDA phase represents an
                      unusual molecular system with π–orbitals oriented
                      parallel to a metal surface. A substantially reduced
                      coupling of these orbitals to Ag(111) electronic levels is
                      conjectured, which will have a major impact on
                      intermolecular couplings and electronically excited state
                      lifetimes.},
