Oxygen-Promoted on-Surface Synthesis of Polyboroxine Molecules

Daniele Toffoli et al. Chemistry. .

Abstract

We present a protocol for the on-surface synthesis of polyboroxine molecules derived from boroxine molecules precursors. This process is promoted by oxygen species present on the Au(111) surface: oxygen atoms facilitate the detachment of naphthalene units of trinaphthyl-boroxine molecules and bridge two unsaturated boroxine centers to form a boroxine-O-boroxine chemical motif. X-ray spectroscopic characterization shows that, as the synthesis process proceeds, it progressively tunes the electronic properties of the interface, thus providing a promising route to control the electron level alignment.

Keywords: Gold reactivity; On-surface synthesis; Oxygen-gold interface; Polyboroxines.
