As a first observation, it becomes evident that the polymers always adsorb within trenches of the reconstructed substrate surface. As prepared, the Au(110) is characterized by a 2×1 reconstruction in which neighboring rows of Au atoms are separated by twice the Au lattice constant a=4.07 Å. Such a reconstruction can be observed in the clean substrate regions of Figure , and its periodicity is shown in the top profile of Figure marked with a circled "1". However, although the mere "as deposited" m1 reactants don't cause any changes to it (Figure ), the surface in the vicinity of the polymers changes into a 3×1 (circled "2" in Figure ) or occasionally also a 4×1 (circled "3" in Figure ) reconstruction as the sample is annealed, with the polymers always embedded within the widened trenches.
