在精确的电化学电位控制下，在金电极表面的三钌簇的自组装单层（SAM）中实现了高选择性的配体交换反应。众所周知，CO 和 NO 分子在许多化学、生物和环境系统中发挥着关键作用，可以通过电化学调节 Ru 位点的电子状态将其有效地引入 SAM 中。这些独特的表面反应比溶液中的传统配体交换反应更方便、更有效，可用于阐明生物系统中的电子转移机制以及分子传感器和设备的开发。
A highly selective ligand exchange reaction is realized in the self-assembled monolayer (SAM) of a triruthenium cluster on a gold electrode surface under precise electrochemical potential control. CO as well as NO molecules, which are known to play key roles in many chemical, biological, and environmental systems, can be efficiently introduced into the SAM by electrochemically tuning the electronic state of the Ru site. These unique surface reactions are more convenient and efficient than conventional ligand exchange reactions in solution and could be used for the elucidation of the electron-transfer mechanism in a biological system as well as in the development of molecular sensors and devices.
