“…The manipulation of organic nanostructures on surfaces through the supramolecular approach has garnered substantial attention in recent decades. − Among the various supramolecular interactions, H-bonding interactions have been extensively harnessed to foster the formation of highly organized two-dimensional (2D) networks. − This has been followed by examples reporting coordination bonding − and dipole–dipole , interactions (Figure a–c). More recently, there has been a notable surge of interest in employing secondary bonding interactions (SBIs), which have a dual nature.…”

Chalcogen bonding interactions (ChBIs) have been widely employed to create ordered noncovalent assemblies in solids and liquids. Yet, their ability to engineer molecular self-assembly on surfaces has not been demonstrated. Here, we report the first demonstration of on-surface molecular recognition solely governed by ChBIs. Scanning tunneling microscopy and ab initio calculations reveal that a pyrenyl derivative can undergo noncovalent chiral dimerization on the Au(111) surface through double Ch•••N interactions involving Te-or Se-containing chalcogenazolo pyridine motifs. In contrast, reference chalcogenazole counterparts lacking the pyridyl moiety fail to form regular self-assemblies on Au, resulting in disordered assemblies.
