“…3,4 Their chemical and thermal stability has permitted studies in ultra high vacuum (UHV) environments resulting in many spectroscopic investigations. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] The possibility to modify the electronic structure of the molecular film allows the tuning of specific properties and this is clearly highly desired to further improve the performance of Pc-based devices. For this reason, the interesting results reported by Craciun et al 19 and already predicted by a theoretical study by Tosatti et al 20 about the observation of an insulator-to-metal transition of Pc films upon alkali intercalation (between 0 and 4 K atoms per molecule) have inspired a number of studies.…”

“…1,2 Their chemical and thermal stability makes them suitable for ultrahigh vacuum ͑UHV͒ studies resulting in many spectroscopic investigations. [3][4][5][6][7][8][9][10][11][12][13] The chemical structure of this group of molecules ͑see Fig. 1͒ is similar to the active sites of chlorophyll, hemoglobin, and different enzymes, making them interesting in biomimetic applications such as catalyst for oxidation reactions.…”

“…Photoelectron spectroscopy of the Cu 2p core level of CuPc shows a distinct shoulder consistent with Cu being stripped from the molecule on Si(111), but not on Si(001) [1,2], while studies of F 16 CuPc show the Cu being removed from the molecule even on on Si(001) [6]. Interestingly, for lead phthalocyanine (PbPc) on Si(111) and Si(001) the reaction is not observed [4]. This is unexpected given that this metal atom is readily removed upon annealing of interface layers [8], and upon deposition on platinum substrates at room temperature [9].…”

“…A number of studies of various MPc and derivatives have been conducted on the Si(111)-(7×7) and Si(001)-2×1 surface [1][2][3][4][5][6]. Photoelectron spectroscopy shows significant changes in the carbon and nitrogen core levels of adsorbed MPc [1,2,4] and substrate auger emission shows changes in surface related features [2], all indicative of a strong interaction between molecule and substrate. Furthermore scanning tunneling microscopy (STM) studies of copper phthalocyanine (CuPc) on Si(111) and Si(001) show individual molecules distributed across the terraces [2,3].…”
