The on-surface synthesis of covalent organic nanosheets driven by reactive metal surfaces leads to strongly adsorbed organic nanostructures, which conceals their intrinsic properties. Hence, reducing the electronic coupling of the organic networks to common- ly used metal surfaces is an important step toward characterization of the true material. We demonstrate that the post-synthetic expo- sure to iodine vapour leads to the intercalation of an iodine mono- layer between covalent polyphenylene networks and Ag(111) sur- faces. The experimentally observed changes from the surface-bound to the detached nanosheets are reproduced by DFT simulations. These findings suggest that iodine intercalation provides a material showing geometric and electronic features substantially closer to the free-standing network.
