Surface-assisted synthesis has become a powerful approach for generation of molecular nanostructures, which could not be obtained via traditional solution chemistry. Nowadays there is an intensive search for reactions that could proceed on flat surfaces in order to boost the versatility and applicability of synthesized nano-objects. Here we propose application of atomic hydrogen combined with on-surface synthesis in order to tune the reaction pathways. We demonstrate that atomic hydrogen could be widely applied: (1) as a cleaning tool, which allows removal of halogen residues from the surface after Ullmann couplings/polymerization, (2) by reaction with surface organometallics to provide stable hydrogenated species, and (3) as a reagent for debromination or desulfurization of adsorbed species.

用原子氢进行表面合成。

表面辅助的合成已经成为用于产生分子的纳米结构,其无法获得的一个功能强大的方法通过传统的溶液化学。如今,人们对在平坦表面上进行的反应进行了深入研究,以提高合成纳米物体的多功能性和适用性。在这里,我们提出结合表面合成使用原子氢的应用,以调节反应路径。我们证明了原子氢可以广泛应用:(1)作为清洁工具,可以在Ullmann偶联/聚合反应后从表面除去卤素残留物;(2)通过与表面有机金属反应以提供稳定的氢化物;以及(3) )作为吸附物质脱溴或脱硫的试剂。
