    • The spot wells of the MALDI-TOF sample plate containing millimolar solutions of the assemblies in different solvents were covered with a thin poly(ethyleneglycol) film. In this way the original constitution of the sample solutions is mostly preserved, and evaporation is kept to a minimum.

    • The rod widths were determined by taking into account the broadening due to the convolution with the SFM tip, as described in: P. Samorí, V. Francke, K. Müllen, J. P. Rabe, Chem. Eur. J. 1999, 5, 2312-2317.

    • The individual supramolecular rods could not be resolved due to the limitation in the SFM resolution and to their tight packing.

    • [5d] the cavitand-based supramolecular polymer is very likely lying on the top of an alkane monolayer (SAM) self-assembled on HOPG, taking advantage of the high surface potential ripple of the underlying SAM.

    • The apparent rod thickness of 0.8 nm is at the lower end end of the expected range. This can be due to both the flattening at surfaces occurring upon adsorption and to imaging artifacts. The latter can include indentation of the supramolecular object by the probing tip as well as the adhesion of the tip to the surface as discussed in: P. Samorf, C. Ecker, I. Gössl, P. A. J. de Witte, J. J. L. M. Cornelissen, G. A. Metselaar, M. B. J. Otten, A. E. Rowan, R. J. M. Nolte, J. P. Rabe, Macromolecules 2002, 35, 5290-5294.
