Supramolecular self-assembly of brominated molecules on a silicon surface

Abstract

Hydrogen and halogen bonds have been associated for the growth of 2D compact supramolecular networks on a silicon surface. These interactions have been elucidated in a complete monolayer of a 4,4′′-dibromo-p-terphenyl (DBT) molecule on a Si(111)–B surface by combining scanning tunneling microscopy (STM) and density functional theory (DFT) calculations.
