Abstract The transfer of functional molecules onto self‐assembled monolayers (SAMs) by means of soft and scanning‐probe lithographic techniques—microcontact printing (μCP) and dip‐pen nanolithography (DPN), respectively—and the stability of the molecular patterns during competitive rinsing conditions were examined. A series of guests with different valencies were transferred onto β‐cyclodextrin‐ (β‐CD‐) terminated SAMs and onto reference hydroxy‐terminated SAMs. Although physical contact was sufficient to generate patterns on both types of SAMs, only molecular patterns of multivalent guests transferred onto the β‐CD SAMs were stable under the rinsing conditions that caused the removal of the same guests from the reference SAMs. The formation of kinetically stable molecular patterns by supramolecular DPN with a lateral resolution of 60 nm exemplifies the use of β‐CD‐terminated SAMs as molecular printboards for the selective immobilization of printboard‐compatible guests on the nanometer scale through the use of specific, multivalent supramolecular interactions. Electroless deposition of copper on the printboard was shown to occur selectively on the areas patterned with dendrimer‐stabilized gold nanoparticles.
