    Feb 22, 2023Thioether polymers are fundamental for a variety of applications. Their synthesis is, however, more challenging than that of other metal-catalyzed reactions due to the reported detachment of the S atom during thermal activation. In this study, it has been demonstrated unambiguously that thermal annealing results in the thioetherification of the 4-bromo-4-mercaptobiphenyl molecule (Br-MBP ...

      The 4´-Bromo-4-mercaptobiphenyl (Br-MBP) molecules have been deposited in ultra-high vacuum conditions (UHV) onto the Au(111) surface previously prepared by cycles of Ar+ ion sputtering and subsequent annealing. A post-annealing of the molecules adsorbed on the Au surface at a temperature in the range of 180-200ºC leads to the

    Indeed, when adsorbed on Au(111) surface, the Br-MBP molecules spontaneously dehydrogenate the sulfhydryl group and form dimer pairs bridged by strong S−Au−S interaction already at room temperature11,13,20−22 (Figure 1b). Evidence of a change in the S−Au bonding interaction between the molecules and the substrate is provided by their

    Feb 2, 2023In Figure Figure1 1, a representative topographic image shows extended zigzagging chains and closed-loop structures formed after the adsorption and annealing of the Br-MBP molecules on Au(111) at 180 °C.Among these, the smallest ring-like structures are hexamers, although heptamers and octamers are not uncommon, suggesting that their formation is not determined by the high-symmetry directions ...
