(a) Calculated adsorption geometry of the double-decker structure (light grey, Cu; dark grey, W; magenta, Nd; blue and green, Pc ligands; with N dark, C medium, H light colour). (b) STM overview showing isolated intact double-decker NdPc2 (A/A*) and decomposed single-decker Pc or NdPc (B/B*) molecules. Two adsorption sites A/A* and B/B* are identified for both species, respectively. Scale bar, 20 nm. (c) STM topography of an NdPc2 molecule and (d) the corresponding calculated STM image. Scale bars in c and d, 1 nm. The used tunnelling parameters are Itunnel=2 nA, Vbias=−1 V in b and Itunnel=2 nA, Vbias=−0.8 V in c. The topography in d is calculated for the energy E–EF=−0.8 eV.
