Abstract
The adsorption of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) on a rutileTiO2(011)-(2 × 1) surface is studied using ultra-high vacuum scanning tunneling microscopy. Theself-assembly process is dominated by the fine interplay between the lateral intermolecularinteractions and the binding to the substrate. By means of temperature-induced change inthe adsorption configuration and the activation of diffusion, the molecules are assembledinto one-dimensional chains oriented along the crystallographic direction.
