Formation of 2D Halogen Bond-Based Supramolecular Assemblies by 1,3,5-Trifluoro-2,4,6-triiodobenzene and 4,4'-Bipyridine N,N'-Dioxide on HOPG Surface.

Halogen bonding interactions are crucial in the design of 2D supramolecular assemblies. In this study, we introduce the N-oxide moiety as a halogen-bonding acceptor for the formation of 2D coassemblies. The monomers 4,4'-bipyridine N,N'-dioxide (BPYD…
