La fonctionnalisation de surfaces de silicium hydrogéné par des films de molécules organiques suscite un intérêt croissant en raison des nombreuses applications potentielles (photovoltaïsme, détection chimique et biochimique, électronique moléculaire...). Dans ce cadre, nous avons cherché à greffer des tétrathiafulvalènes ou des complexes dithiolène de platine à ligand bipyridine, électroactifs, sur cette surface par hydrosilylation d’alcynes. Nous avons montré que ces composés organiques étaient bien immobilisés par une liaison robuste Si-C et nous avons noté la présence de plusieurs états redox stables et réversibles associés aux molécules greffées. Les méthodes de greffage direct et de post-fonctionnalisation de monocouches, ont permis l’obtention de films denses stables aux constantes de transfert de charge élevées. / The functionalization of silicon surfaces by thin layers of organic molecules raises increasing interest due to the large extent of potential applications (photovoltaics, chemical and biochemical detection, molecular electronics and so on). In this context, we have prepared TTF and platinum dithiolene complex-modified silicon surfaces through a hydrosilylation reaction between hydrogen-terminated silicon and alkyne-terminated precursors. We have shown that these organic compounds were covalently bound to the surface through a robust Si-C bond. We have demonstrated that the electroactivity of the grafted molecules characterized by several reversible one-electron systems was maintained after the immobilization step. Post-functionalization and direct grafting reactions lead to dense and stable films, with high values of electron-transfer rate constants.
