Image of FIG. 1.
FIG. 1.

Thiol-AB molecule (trans isomer).

Image of FIG. 2.
FIG. 2.

STM topographic images of thiol-AB molecules on Au(111) at (−2 V, 50 pA): (a) a typical large-scale image and [(b)–(e)] closeup images of four predominant molecular species. (b) Short-straight, (c) short-bent, (d) long-straight, and (e) long-bent species are shown. No significant difference between filled and empty state images is observed.

Image of FIG. 3.
FIG. 3.

STM topographic image of thiol-AB molecules on Au(111) taken at (−2 V, 25 pA). A large number of flower-shaped species are observed. The inset shows a closeup view of area outlined by a dashed line.

Image of FIG. 4.
FIG. 4.

A sequence of images showing change in a flower-shaped molecule as temperature is varied. Images taken at (a) 55, (b) 34, and (c) 50 K, respectively, with all other imaging conditions the same (−2 V, 25 pA). (d) Total number of flower-shaped molecules observed at different temperatures normalized by total observation area and sample coverage. A sigmoid fit is also shown as a dashed line (see text).

Image of FIG. 5.
FIG. 5.

Proposed structural models for observed thiol-AB species are superimposed on measured STM images previously shown in Fig. 2: (a) short-straight, (b) short-bent, (c) long-straight, and (d) long-bent species. (e) Two possible bonding configurations for long-straight and long-bent species. (f) Sketch of possible pi-stacking configuration for short-bent morphology.
