“…For the investigation of the chemical reactivity at interfaces X-ray photoelectron spectroscopy (XPS) is a suitable method. It was shown that interfaces between divalent MPcÕs and inorganic semiconductors often exhibit weak bonding even in the presence of dangling bonds on the inorganic semiconductor surfaces because of the closed-shell character of the MPcÕs molecules [1][2][3][4][5]. On the other hand, a strong chemical reaction was observed for MPcÕs on more reactive substrates, like CuPc/Al(0 0 1) [6], CuPc/indium tin oxide (ITO) [7], CuPc/Si(111) [1] and CuPcF 4 /Ag [8].…”

“…A strong influence of the substrate on the growth morphology of MPc thin films is well established. In particular, both the chemical nature and the surface geometry of the substrate are important parameters [2,3]. It is well known that a flat-lying deposition is the most probable configuration for the first deposited layer [4] in presence of strong molecule/substrate interaction [5], while, when layered materials (i. e. mica or graphite) are employed as substrates, the CuPc molecules weakly interact, favouring a self-assembling behavior, and giving rise to columnar stacks with a different orientation angle [6].…”

We present the growth morphology, the long range ordering, and the evolution of the valence band electronic states of ultra-thin films of copper phthalocyanine (CuPc) deposited on the Au(110)-(1x2) reconstructed surface, as a function of the organic molecule coverage. The Low Energy Electron Diffraction (LEED) patterns present a (5x3) reconstruction from the early adsorption stages. High-Resolution UV photoelectron spectroscopy (HR-UPS) data show the disappearance of the Au surface states related to the (1x2) reconstruction, and the presence of new electronic features related to the molecule-substrate interaction and to the CuPc molecular states. The CuPc highest occupied molecular orbital (HOMO) gradually emerges in the valence band, while the interface electronic states are quenched, upon increasing the coverage.

“…It is most easily achieved by passivating the dangling bonds of the semiconductor surface prior to molecular thin film growth [3]. However, recent reports have shown that some molecules, including various phthalocyanines and perylenes, also adopt ordered structures on unpassivated III-V semiconductor substrates [4][5][6][7][8][9][10]. The implication in these systems is that the molecule-substrate interaction must be sufficiently weak to allow significant lateral diffusion of the molecules across the surface and formation of an ordered thin film structure.…”
