On‐Surface Covalent Coupling in Ultrahigh Vacuum

Abstract

Beyond supramolecular self-assembly: On-surface covalent coupling of organic precursors is a powerful method to obtain 1D or 2D robust molecular arrays on a substrate (see picture) that have numerous potential applications in nanotechnology. Significant advances have recently been made in this field including imine formation, dehydration of boronic acids, esterification, as well as radical and carbene coupling reactions.
