Surface modification represents an active field of research that finds applications, amongst others, in the development of medical devices, sensors and biosensors, anti-biofouling materials, self-cleaning surfaces, surfaces with controlled wettability, corrosion resistance, heterogeneous catalysis and microelectronics. For some applications, surface functionalization with a nanometric-size monolayer is desired. In this review, efforts to covalently functionalize a wide array of surfaces with calixarenes bearing diazonium groups are described. More specifically, methodologies to obtain monolayers of calix[4 or 6]arene derivatives on conductive, semi-conductive or insulating surfaces as well as on nanoparticles are presented. The main advantages of this general surface modification strategy (i.e. formation of true monolayers that can be post-functionalized, high robustness and control over the composition of the calixarene-based coating) and its current scope of applications and future challenges are discussed.
表面修饰是一个活跃的研究领域，其应用包括医疗器械、传感器和生物传感器、抗生物污染材料、自清洁表面、具有可控润湿性的表面、耐腐蚀、多相催化和微电子学等领域。对于某些应用，希望用纳米级单层对表面进行功能化。在这篇综述中，描述了用带有重氮基团的杯芳烃对各种表面进行共价功能化的努力。更具体地说，介绍了在导电、半导电或绝缘表面以及纳米颗粒上获得杯[4 或 6]芳烃衍生物单层的方法。讨论了这种通用表面修饰策略（即形成可以后功能化的真正单层、高稳定性以及对杯芳烃基涂层组成的控制）及其当前应用范围和未来挑战的主要优点。
