Fig. 1. (Color online) (a) A 6.7×6.7  nm² STM image of Pt-OEP adsorbed on the bare HOPG surface from 1-phenyloctane solution. The tip bias is 1  V and the tunneling current is 0.6  nA. (b) A line scan measured on Pt-OEP molecules shown in (a) (dotted blue line). The peak to peak distance is the lattice spacing between two molecules and it is about 1.2  nm. (c) A 3.7×3.7  nm² STM image of Pt-OEP adsorbed on bare HOPG surface from benzene solution. (d) Two line scans measured along the and directions. The tip bias is 0.8  V and the tunneling current is 0.6  nA. Vectors and show the symmetry directions of the molecular layers. A model of the Pt-OEP molecule is overlaid on the STM images shown in (a) and (c). Since it is not possible to extract the spatial configuration of the ethyl groups, their position is arbitrarily assigned. First citation in article

Fig. 2. (Color online) (a) A 150×150  nm² STM image of Pt-OEP adsorbed on 5-OIA SAM. Circled regions show boundaries between differently aligned 5-OIA molecules. (b) A line scan taken over Pt-OEP molecules. (c) A 10×10  nm² STM image of Pt-OEP adsorbed on 5-OIA SAM. For both STM images, the tip bias and tunneling current are 1  V and 0.6  nA, respectively. A model of the Pt-OEP molecule is inserted in the STM image shown in (c). Since it is not possible to extract the spatial configuration of the ethyl groups, their position is arbitrarily assigned.

Fig. 3. (Color online) (a)–(e) are sequentially measured 150×150  nm² STM images of the same region. Blue circle and square indicate regions where a change in the monolayer is observed. (f) There is a lapse time of about half an hour between (e) and (f). During this time, various small scale images were measured around this region. First citation in article
