This review provides a comprehensive survey of the derivatization of hydrogen-terminated, oxide-free silicon surfaces with electroactive assemblies (from molecules to polymers) attached through strong interactions (covalent, electrostatic, and chimisorption). Provided that surface modification procedures are thoroughly optimized, such an approach has appeared as a promising strategy toward high-quality functional interfaces exhibiting excellent chemical and electrochemical stabilities. The attachment of electroactive molecules exhibiting either two stable redox states (e.g., ferrocene and quinones) or more than two stable redox states (e.g., metalloporphyrins, polyoxometalates, and C60) is more particularly discussed. Attention is also paid to the immobilization of electrochemically polymerizable centers. Globally, these functional interfaces have been demonstrated to show great promise for the molecular charge storage and information processing or the elaboration of the electrochemically switchable devices. Besides, there are also some relevant examples dealing with their activity for other fields of interest, such as sensing and electrochemical catalysis.
这篇综述全面介绍了通过强相互作用（共价键、静电相互作用和化学吸附）将附着有电活性组件（从分子到聚合物）的氢封端、无氧化物硅表面进行衍生化。只要表面修饰程序得到彻底优化，这种方法似乎是一种很有前途的策略，可以得到具有优异化学和电化学稳定性的高质量功能界面。特别讨论了附着具有两种稳定氧化还原态（例如二茂铁和醌）或两种以上稳定氧化还原态（例如金属卟啉、多金属氧酸盐和 C60）的电活性分子。还注意到了电化学聚合中心的固定化。总的来说，这些功能界面在分子电荷存储和信息处理或电化学可切换器件的设计方面显示出巨大的应用潜力。此外，还有一些相关的例子涉及它们在其他感兴趣的领域的活性，如传感和电化学催化。
