Figure 3

(a) STM topographies of the same surface area before and after pulling off a single polyfluorene initially lying along an fcc stripe of the herringbones reconstruction of Au(111). (b) Recorded frequency shift of an oscillating force sensor while retracting the tip after contacting. The detachment event was indicated by an arrow. (c) Magnification around Z=17.5 nm. (d) Schematic representation of the interactions acting while pulling up the polymer. (e) Calculated Z distance dependence of the normal force gradient.
