• reported by us [36] and those of perylenetetracarboxylic dianhydride (PTCDA) solid crystalline films (4 × 10−2 cm2/s) [41]. The exciton diffusion lengths in the assembled material are also comparable or higher than the reported values for 2D PDI crystals (120 nm) [36], PTCDA films (61 nm) [52], and PDI J

Our results confirm the (4√2 × 5√2)R45° superstructure of PTCDA/Cu(100) reported by A. Schmidt et al. [J. Phys. Chem. 1995, 99,11770–11779]. However, contrary to Schmidt

• et al., we have no indication for a dissociation of the PTCDA upon adsorption, and we propose a detailed structure model with two intact PTCDA molecules within the unit cell. Domains of high lateral order are obtained, if the deposition is performed at 400 K. For deposition at room temperature, a

• atomic layers for the adsorption on the M(110) surfaces. For each surface we performed calculations for different adsorption sites and orientations of the benzene molecule. Geometry optimizations were performed with the PBE-D3 method, which was already used for the study of PTCDA on the Ag(111), Ag(100

• determined distances are available for these systems. However, previous experimental and theoretical studies of PTCDA on the Ag(111), Ag(100) and Ag(110) surfaces [9][10] indicate that the PBE-D3 and PBE-D3(BJ) approaches give accurate adsorption distances. A closer look at the optimized structures reveals
