The (electro)chemical grafting of a polyfluorinated calix[4]arene on gold, polypropylene and glass is reported. The modified surfaces were characterized by ellipsometry, atomic force microscopy (AFM), and by X-ray photoelectron spectroscopy (XPS). A nanometric, robust and uniform monolayer of covalently surface-bound calix[4]arenes was obtained on the three different materials. For all surfaces, contact angles higher than 110° were recorded, highlighting the hydrophobic character given by this ∼2 nm thin organic monolayer. Remarkably, the contact angle values remained unchanged after 18 months under a laboratory atmosphere. The results presented herein thus present an attractive and sustainable strategy for bringing hydrophobic properties to the interface of a wide range of materials.

通过纳米共价结合的有机层获得坚固的疏水金、玻璃和聚丙烯表面

报道了多氟化杯[4]芳烃在金、聚丙烯和玻璃上的（电）化学接枝。通过椭偏仪、原子力显微镜 (AFM) 和 X 射线光电子能谱 (XPS) 对改性表面进行了表征。在三种不同的材料上获得了共价表面结合的杯[4]芳烃的纳米级、坚固且均匀的单层。对于所有表面，记录了高于 110° 的接触角，突出了这种约 2 nm 薄有机单层赋予的疏水特性。值得注意的是，在实验室气氛下 18 个月后接触角值保持不变。因此，本文提出的结果提出了一种有吸引力且可持续的策略，可将疏水特性带入多种材料的界面。
