    • The observation of only one species with a rather small hydrodynamic radius might be the result of a specific dimerization where the macrocycles are arranged face-to-face and rotated by 90°, so that the dendritic side groups efficiently block the top and bottom of the dimer and prevent a further growth of the aggregate. A similar observation has been made on other macrocycles. Cf.

This image, in which only raw features are visible, is subtracted from the original topography data, yielding the enhanced visibility of the small features in the <20 nm size regime. The deconvolution was done with the SPIP software package, ImageMetrology.

    • Lateral dimensions (i.e., widths) of individual objects are typically overestimated by AFM due to a limited tip radius and an interaction range being typically larger than the measured dimensions. However, the width of particles within a periodic lattice is measured correctly via the lattice distance. For further details see, e.g.

    • In particular, as soft tapping conditions (i.e., small free amplitude and small damping) are chosen, the determined heights represent a good approximation for the tube diameter. Noteworthy, the force applied by the AFM tip in the amplitude-mode (AM) exerts a certain pressure on the sample and may cause a deformation of soft matter (cf.:;). Additionally, the influence of the substrate/molecule interaction on the tube cross section is not clear at present. Cf.:; Macromolecules 2002, 35, 4282-4288

    • At the present stage, we assume that different interaction strengths (as discussed above) lead to unlike adsorption behavior of aggregates of 2a on substrates that are different in polarity or able to support commensurate adlayers due to specific interatomic distances of the surface crystal lattice. Additionally, contact electrification can be discussed as an origin for the adsorbate-substrate interaction for the particular case of polystyrene on HOPG. The term "contact electrification" describes electrical charging of PS on a HOPG surface due to accessibility of respective acceptor states in PS from the Fermi level of HOPG. (see, e.g.:;). However, presently the role of contact electrification on the quantitative description of the adsorbate-substrate interactions of aggregates of 2a with HOPG is unclear
