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.
