a I–a III, b I–b III, c I–c III, d I–d III Molecules, AFM images and Laplace-filtered AFM images with superimposed models of Int 6 (C20Cl2), C20, Int 7 (C30Cl4) and C30. AFM tip offsets Δz: +0.5 Å, +0.4 Å, +0.4 Å, +0.3 Å for (a II–d II). Reference set points of Δz: I = 0.5 pA, V = 0.3 V for all AFM images. The scale bar in a II applies to (a–d) images.
