Description
Based on scanning tunneling microscopy experiments combined
with density functional theory, we report the formation and the
electronic structure of porous binary supramolecular networks on
Au(111). The two triphenylamine derivatives with identical scaffolds
intermix due to a maximization of the overall number of H-bonds
instead of an optimization of the H-bond strength in the bonding
motif. The HOMO–LUMO gap is defined by both molecules, which
is typical for electron donor–acceptor networks.
