在表面上自组装分级纳米结构是一种很有前途的策略，用于开发广泛的新技术，如能量存储设备和传感器。在这项工作中，我们表明，两亲性，有机官能化的混合聚氧乙烯醚自发地自组装在玻璃碳，氧化石墨烯，和高度定向的热解石墨，以创建分层氧化还原活性纳米结构。这些超分子，纳米结构的组件的电化学行为和稳定性进行了详细的探讨，并通过全面的光学和光谱分析确定其形态。这些混合纳米材料的亲水性和疏水性碳的自发组装进行了比较，我们讨论了如何这种策略可能是一种新的，简单的，有效的方法制造分层修饰电极表面。
The self-assembly of hierarchical nanostructures on surfaces is a promising strategy for the development of a wide range of new technologies, such as energy-storage devices and sensors. In this work we show that amphiphilic, organofunctionalized hybrid polyoxometalates spontaneously self-assemble on glassy carbon, graphene oxide, and highly oriented pyrolytic graphite to create hierarchical redox-active nanostructures. The electrochemical behaviour and stability of these supramolecular, nanostructured assemblies is explored in detail and their morphology is determined by comprehensive optical and spectroscopic analyses. The spontaneous assembly of these hybrid nanomaterials on both hydrophilic and hydrophobic carbons is compared and we discuss how this strategy may be a new, simple, and effective method of fabricating hierarchically modified electrode surfaces.
