Covalent immobilization of fluoride-encapsulating octaphenyl silsesquioxane F⁻@Ph₈T₈ on glassy carbon (GC) was achieved using a new ambifunctional grafting agent, iodomethyltrimethylsilane TMSCH₂I. This grafting method did not require any pre-grafting functionalization of the Ph-trimmed substrate; instead, the GC interface was anodically covered with CH₂I groups whose ensuing reduction in the presence of F⁻@Ph₈T₈ resulted in the covalent grafting of the phenyl silsesquioxane cage onto the GC surface via the CH₂ linker(s). The resulting ionic interface can be used to detect exposure to Li⁺- and H⁺-containing media. The proposed electrochemical process offers a general method for covalent binding of two (poly)aromatic substrates by a methylene bridge.
