We report a sono-Fenton strategy to mediate the supramolecular assembly of metal–phenolic networks (MPNs) as substrate-independent coatings using phenol and phenyl derivatives as building blocks. The assembly process is initiated from the generation of hydroxyl radicals (^.OH) using high-frequency ultrasound (412 kHz), while the metal ions synergistically participate in the production of additional ^.OH for hydroxylation/phenolation of phenol and phenyl derivatives via the Fenton reaction and also coordinate with the phenolic compounds for film formation. The coating strategy is applicable to various phenol and phenyl derivatives and different metal ions including Fe^II, Fe^III, Cu^II, and Co^II. In addition, the sono-Fenton strategy allows real-time control over the assembly process by turning the high-frequency ultrasound on or off. The properties of the building blocks are maintained in the formed films. This work provides an environmentally friendly and controllable method to expand the application of phenolic coatings for surface engineering.

Sono-Fenton 化学将苯酚和苯基衍生物转化为用于工程表面涂层的多酚

我们报告了一种 sono-Fenton 策略，以使用苯酚和苯基衍生物作为构建单元来介导金属-酚网络 (MPN) 的超分子组装，作为与基材无关的涂层。组装过程是从羟基自由基的生成启动（^。使用高频超声（412 kHz）的OH），而金属离子的协同参与生产的附加^。OH 通过芬顿反应对苯酚和苯基衍生物进行羟基化/酚化，并与酚类化合物配合形成薄膜。该涂层策略适用于各种苯酚和苯基衍生物以及不同的金属离子，包括Fe ^II、Fe ^III、Cu ^II和Co ^{II 。}. 此外，sono-Fenton 策略允许通过打开或关闭高频超声波来实时控制装配过程。在形成的薄膜中保持了结构单元的特性。这项工作为扩大酚醛涂料在表面工程中的应用提供了一种环境友好且可控的方法。
