• . First, 5 mL of a lipid chloroform solution (5 mg/mL) were vacuum dried in a glass vessel. Then, a phosphate buffered saline (5 mL, 0.9% NaCl, 100 mM phosphate buffer, pH 7.2) was added to form multilamelar vesicles. Sonication and extrusion (Avanti Polar Lipids, U.S.A.) were performed to produce

• intermittent tapping mode. The first mode used in AFM was the contact mode. Manipulation of large C60 islands on NaCl was performed by Lüthi et al. using contact AFM [11]. Even if the shear between islands and crystal surface can be derived from the frictional forces experienced by the AFM tip while scanning

• molecular assemblies can be formed. The electronic decoupling of the molecules by one or two monolayers of KBr from the Cu(111) substrate is found to be insufficient to enable comparable growth conditions to bulk ionic materials. Keywords: directed growth; KBr; molecular wires; NaCl; nc-AFM; porphyrin

• NaCl thin films have already proved their importance as homogeneous ultrathin spacer layers to separate single molecules from the metal substrate [14][15][16]. Nevertheless, complete electrical decoupling of such devices from the substrate requires bulk insulators or thick insulating films. Several

In the work presented here we focus on the influence of the substrate on the growth process of meso-(4-cyanophenyl)-substituted Zn(II) porphyrin molecular wires self-assembled on KBr(001) and NaCl(001) studied by nc-AFM. We found that the lattice spacing of the ionic crystal has a direct impact
