Experimental (a) and simulated AFM (b) image of a single molecule 1 on Au(111) surface. Scanning parameters of (a): Setpoint before switching off the feedback: Vs = 0.5 V, It = 400 pA. Scale bar: 4 Å. (c-d) Force spectroscopic measurements taken at different sites over a single molecule 2. The height difference between the cyclized area (lower panel c) and non-cyclized area (upper panel c) is ~150 pm, indicating that the non-cyclized benzylic groups remain intact after cyclizing the adjacent corner. Numbers indicate the positions where the spectra are recorded. Scanning parameters: Vs = 1 mV. Setpoint before switching off the feedback: Vs = 0.5 V, It = 400 pA. Scale bar: 4 Å.
