“…51,52,168 For further details on the early body of work on the photochemical hydrosilylation, the reader should consult the comprehensive reviews of Buriak. 27,28 Here we will mainly focus our discussion on more recent advances, while trying to bring to the attention of the reader the need for conclusive data to resolve the details of the surface hydrosilylation reaction mechanism, both under illumination and thermal conditions. Interestingly, as discovered by Stewart and Buriak 170 for porous silicon and more recently reported by Sudho¨lter and co-workers for crystalline Si(100) and Si (111) substrates (Fig.…”

“…Hydrosilysation [75] of SiÀH with neat alkene was first reported in 1993 [76] and several other methods were reported since then. Excellent reviews on the chemistry of wet [77][78][79] and gas-phase [10,31,80,81] adsorption have been published. The SiÀH bond needs to be activated for the reaction, which can be done by heating (150À200 8C), [44,71] UV illumination, [31,69] Lewis acid-mediated initiators, [42] or electrochemistry.…”

Molecules on Si: Electronics with Chemistry

Basic scientific interest in using a semiconducting electrode in molecule‐based electronics arises from the rich electrostatic landscape presented by semiconductor interfaces. Technological interest rests on the promise that combining existing semiconductor (primarily Si) electronics with (mostly organic) molecules will result in a whole that is larger than the sum of its parts. Such a hybrid approach appears presently particularly relevant for sensors and photovoltaics. Semiconductors, especially Si, present an important experimental test‐bed for assessing electronic transport behavior of molecules, because they allow varying the critical interface energetics without, to a first approximation, altering the interfacial chemistry. To investigate semiconductor‐molecule electronics we need reproducible, high‐yield preparations of samples that allow reliable and reproducible data collection. Only in that way can we explore how the molecule/electrode interfaces affect or even dictate charge transport, which may then provide a basis for models with predictive power.To consider these issues and questions we will, in this Progress Report, review junctions based on direct bonding of molecules to oxide‐free Si. describe the possible charge transport mechanisms across such interfaces and evaluate in how far they can be quantified. investigate to what extent imperfections in the monolayer are important for transport across the monolayer. revisit the concept of energy levels in such hybrid systems.

“…The understanding and the manipulation of silicon surfaces2 are key aspects of silicon‐based technologies 3. Stable siliconoids4 are unsaturated neutral silicon clusters5 that reproduce the characteristic structural features of silicon nanoparticles and surfaces in the molecular regime, in particular the presence of one or more unsubstituted vertices 6.…”

Isolation and Versatile Derivatization of an Unsaturated Anionic Silicon Cluster (Siliconoid)

The characteristic features of bulk silicon surfaces are echoed in the related partially substituted—and thus unsaturated—neutral silicon clusters (siliconoids). The incorporation of siliconoids into more‐extended frameworks is promising owing to their unique electronic features, but further developments in this regard are limited by the notable absence of functionalized siliconoid derivatives until now. Herein we report the isolation and full characterization of the lithium salt of an anionic R5Si6‐siliconoid, thus providing the missing link between silicon‐based Zintl anions and siliconoid clusters. Proof‐of‐principle for the high potential of this species for the efficient transfer of the intact unsaturated R5Si6 moiety is demonstrated by clean reactions with representative electrophiles of Groups 13, 14, and 15.
