A new heteroleptic polypyridyle Ru(II) complex was synthesized and deposited on surface by the diazonium electroreduction process. It yields to the covalent grafting of a monolayer. The functionalized surface was characterized by XPS, electrochemistry, AFM, and STM. A precise organization of the molecules within the monolayer is observed with parallel linear stripes separated by a distance of 3.8 nm corresponding to the lateral size of the molecule. Such organization suggests a strong cooperative process in the deposition process. This strategy is an original way to obtain well-controlled and stable functionalized surfaces for potential applications related to the photophysical properties of the grafted chromophore. As an exciting result, it is the first example of a self-organized monolayer (SOM) obtained using diazonium electroreduction.
一种新型的杂多吡啶钌（II）配合物通过重氮电化学还原过程被合成并沉积在表面上。这导致了单层的共价接枝。功能化表面通过 XPS、电化学、AFM 和 STM 进行了表征。在单层内，分子以平行的线性条纹排列，条纹之间的距离为 3.8nm，对应于分子的横向尺寸。这种组织表明在沉积过程中存在强烈的协同作用。这种策略是获得具有潜在应用前景的光物理性质的接枝发色团的良好控制和稳定功能化表面的一种原始方法。作为一个令人兴奋的结果，这是使用重氮电化学还原获得的自组装单层（SOM）的第一个例子。
