a I–a III, b I–b III, c I–c III Molecules, AFM images and Laplace-filtered AFM images with superimposed models of a C20 with Int 6 (C20Cl2), Int 8 (C40Cl2), Int 9 (C40Cl2). AFM tip offsets Δz: +0.4 Å, +0.4 Å, +0.6 Å for (a II–c 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–c) images.
