The covalent modification of the metallic phase of MoS with a Hamilton-type ligand is presented, transforming MoS to a recognition platform which is able to embrace barbiturate moieties via hydrogen bonding. The successful hydrogen bonding formation is easily monitored by simple electrochemical assessments, if a ferrocene-labeled barbiturate analogue is utilized as a proof of concept. Full spectroscopic, thermal, and electron microscopy imaging characterization is provided for the newly formed recognition system, along with valuable insights concerning the electrochemical sensing. The given methodology expands beyond the sensing applications, confidently entering the territory of supramolecular interactions on the surface of 2D transition metal dichalcogenides. The well-designed host-guest chemistry presented herein, constitutes a guide and an inspiration for hosting customized-structured functional building blocks on MoS and its relatives via hydrogen bonding, opening up new opportunities regarding potential applications.
本文介绍了用汉密尔顿型配体对二硫化钼金属相进行共价修饰，将二硫化钼转变为一个识别平台，该平台能够通过氢键容纳巴比妥酸部分。如果使用二茂铁标记的巴比妥酸类似物作为概念验证，则通过简单的电化学评估就能轻松监测到成功形成的氢键。为新形成的识别系统提供了完整的光谱、热学和电子显微镜成像表征，以及有关电化学传感的宝贵见解。所给出的方法不仅适用于传感应用，还自信地进入了二维过渡金属二硫属化物表面超分子相互作用的领域。本文所展示的精心设计的主客体化学，为通过氢键在二硫化钼及其相关材料上容纳定制结构的功能构建块提供了指导和灵感，为潜在应用开辟了新的机会。
