The surface coverage and mol. composition of redox-active mols. anchored on conductive surfaces regulate the kinetic and thermodn. parameters of charge transfer reactions, providing a means to tune the electrochem. properties of hybrid materials. Herein, anchoring strategies and structural properties of redox-active probes, derived from ferrocene (Fc) and naphthalene diimide (NDI), regulate the electrochem. properties of functionalized p-doped Si(111) surfaces. Covalent functionalization of H-terminated Si(111) surfaces with Fc and NDI affords redox-active hybrid interfaces characterized through microscopy, spectroscopy, and voltammetry methods. Mol. design and synthetic grafting strategies modulate the electrochem. properties of the Fc-functionalized Si surfaces with a much higher (∼25 times) surface coverage (1.25 × mol. cm-2) for 1-step photografting compared to divergent synthetic routes. The thermal grafting of an alkadiyne followed by click reaction with ferrocenyl-azide leads to one of the highest surface coverages ( 9.97 × 10-10 mol cm-2) of organo-Fe reported and a significant anodic shift of the half-potential (>350 mV) compared to photografting methods. Similar experiments with NDI units exhibited electrochem. properties that diverge from those recorded for NDI in solution The results presented herein offer access to novel redox-active Si interfaces that evidence tunable electrochem. properties of potential interest for microelectronics applications.
