    • Generally, a molecular printboard is a SAM of receptor molecules that have specific recognition sites, for example, molecular cavities, at which one can immobilize molecules from aqueous solutions through specific and directional supramolecular interactions.

    • See guest 3 (Scheme 1). This calix[4]arene derivative has guanidinium functionalities at the upper rim to increase water solubility. Poly(ethylene glycol) (PEG) linkers at the lower rim space out the two adamantyl functionalities in order to allow this molecule to form inclusion complexes with two neighboring β-CDs on the β-CD SAM (lattice constant β-CT ≈ 8 nm), while water solubility is retained and nonspecific interactions with the printboard are prevented.

    • x) changes the mechanical and adhesive properties of the stamp. The resulting change in deformation characteristics of the PDMS stamp under slight pressure, in order to make conformal contact between the stamp and the substrate, is the most probable cause affecting accurate pattern reproduction of the original stamp features (10 μm with 5 μm spacing). See the printing results of line patterns (about 9 μm with 6 μm spacing, Figure 2 and Figure 3).

    • Use of the per-β-CD complex of 4b is necessary to increase its water solubility (conditions: excess of native β-CD in water at pH 2) to obtain sufficiently concentrated ink solutions for μCP and DPN on the molecular printboard.

    • Relative humidity was found to play an important role in our DPN experiments, since all successful writing experiments were carried out at humidities above 40%. These results support the currently accepted view that relative humidity is essential to the success of DPN. See: S. Rozhok, R. Piner, C. A. Mirkin, J. Phys. Chem. B 2003, 107, 751-757.
