Abstract

Growth of a hybrid inorganic–organic layered structure on the Au(111) surface using a one-step solution growth is reported. The hybrid structure is consist of 4,4′-bipyridine [4,4′-BiPyH2]2 + cations, Cl anions and Au adatoms, provided from substrate by means of the adsorbate-induced surface phase transition of a surface reconstruction. Its surface and bulk structures were characterized by scanning tunneling microscopy (STM), secondary ion mass spectrometry (SIMS), and Raman spectroscopy. STM results reveal growth of the first [4,4′-BiPyH2]2 + layer on top of the [Formula presented] chlorine overlayer formed on the Au(111) surface. These two layers are found to provide a platform for a following three-dimensional growth facilitated by hydrogen bonding, aurophilic and π–π stacking interactions.
