“…However, for most crystal faces approximately one in every two silicon atoms possesses an alkyl chain in a well formed layer and crudely the layers can be regarded as similar. 72 The disadvantage of this system is however it can prove difficult to achieve good quality layers on silicon without the formation of some oxide. 73 As any silicon oxide will influence the electronic properties of molecular devices on planar silicon 74 and accelerate the degradation of porous silicon in aqueous media, 75 the challenge is to prepare the layers without any oxidation of the silicon.…”

The modification of surfaces with self-assembled monolayers (SAMs) containing multiple different molecules, or containing molecules with multiple different functional components, or both, has become increasingly popular over the last two decades. This explosion of interest is primarily related to the ability to control the modification of interfaces with something approaching molecular level control and to the ability to characterise the molecular constructs by which the surface is modified. Over this time the level of sophistication of molecular constructs, and the level of knowledge related to how to fabricate molecular constructs on surfaces have advanced enormously. This critical review aims to guide researchers interested in modifying surfaces with a high degree of control to the use of organic layers. Highlighted are some of the issues to consider when working with SAMs, as well as some of the lessons learnt (169 references). 2011 The Royal Society of Chemistry.

“…This process results in hydrogen-terminated, oxide-free silicon substrates with Si-H groups. The reaction of Hterminated silicon surfaces with alkenes and alkynes can be performed by making use of high temperatures, UV and visible light irradiation, electrochemistry, hydrosilylation catalysts (e.g., AlCl 3 ), and chemomechanical scribing, as summarized in different reviews (Buriak, 2002;Stutzmann, 2006;Hamers, 2008;Ciampi, 2010).…”

“…We have recently shown that the modification of hydrogen terminated Si(100) using 1,8-nonadiyne 1 (Scheme 1) forms a highly stable monolayer on the silicon surface, [17][18] which protects the underlying silicon from oxidation even in aqueous electrolytes under the influence of oxidising potentials [8][9]. The acetylenetermianted Si(100) surface may then be readily functionalized with a broad range of aryl and alkyl azides [19].…”

“…step-wise) approaches appear to be suitable to producing chemically well-defined silicon-based redox SAMs, only a limited number of "wetchemistry" coupling procedures, nominally amide chemistrybased [10], or Cu(I)-catalyzed alkyne-azide cycloaddition (i.e. "click" [14][15]) reactions [8], have been exploited in the preparation of such architectures [16].

Tethered osmium bypiridine-pyridine complexes [Os(bpy)2Clpy-R] were prepared from chemically modified non-oxidized silicon (100) electrodes. Pyridinyl groups at the distal end of self-assembled monolayers (SAMs)-modified silicon surfaces were used to coordinatively bind a representative osmium bipyridil complex precursor [Os(bpy)2Cl2]. SAMs presenting the putative osmium ligand were prepared by a step-wise procedure using click reactions of acetylene-terminated alkyl monolayers and isonicotinic acid azide derivatives. The redox properties of the modified Si(100) electrodes were characterized using cyclic voltammetry. 2010 IEEE. . SAMs presenting the putative osmium ligand were prepared by a stepwise procedure using 'click' reactions of acetylene-terminated alkyl monolayers and isonicotinic acid azide derivatives. The redox properties of the modified Si(100) electrodes were characterized using cyclic voltammetry.
