A Supramolecular Network as Sacrificial Mask for the Generation of a Nanopatterned Binary Self‐Assembled Monolayer

Abstract

A supramolecular hydrogen-bonded network adsorbed on Au(111) can corral thiol self-assembled monolayers (SAMs) inside its pores. Enhancing the thermodynamic stability of these SAM nanoislands by Cu underpotential deposition allows selective replacement of the network by a second thiol species. The resulting binary SAM (see image) retains the periodicity and symmetry of the original supramolecular mask.
