Covalent SiC grafting of a silatrane cage to a carbon‐based interface provides a truly conjugated benzyl‐type system in which the 3 c–4 e orbital of the silatrane interacts with the macroscopic π‐type substituent (graphite C sp2 network) through hyperconjugation. This process, studied by voltammetry, EIS, FTIR, SEM and DFT modeling, allows one to build carbon‐based conducting interfaces with electronically conjugated molecular extensions. Non‐conjugated covalent grafting of an alkyl silatrane moiety provides chemically stable functional interfaces that have good promise for electrochemically‐driven applications, for example, electrochemical spin‐writing.
