“…14,15,[32][33][34] Chlorosilane head groups of the OTS molecules are prone to react with both the terminal amine group of APTMS and the -OH and COO -groups of citrate capping the NPs. [35][36][37] Moreover, OTS can polymerized laterally, though siloxane bonds, forming a capping layer over the surface and NPs. Evidence of the correct grafting of OTS is the observation of an increase of the water contact angle from ∼30-40° for APTMS/NPs surface to ∼90-100° after silanization.…”

Abstract.We report on an artificial synapse, an organic synapse-transistor (synapstor) working at 1 volt and with a typical response time in the range 100-200 ms. This device (also called NOMFET, Nanoparticle Organic Memory Field Effect Transistor) combines a memory and a transistor effect in a single device. We demonstrate that short-term plasticity (STP), a typical synaptic behavior, is observed when stimulating the device with input spikes of 1 volt. Both significant facilitating and depressing behaviors of this artificial synapse are observed with a relative amplitude of about 50% and a dynamic response < 200 ms. From a series of in-situ experiments, i.e. measuring the current-voltage characteristic curves in-situ and in real time, during the growth of the pentacene over a network of gold nanoparticles, we elucidate these results by analyzing the relationship between the organic film morphology and the transport properties. This synapstor works at a low energy of about 2 nJ/spike. We discuss the implications of these results for the development of neuro-inspired computing architectures and interfacing with biological neurons.

“…Furthermore, Maoz et al developed a unique technique for preparing multilayers. 19 Their process was based on the formation of alkylsilane bilayers from alkyltrichlorosilanes within the polar interlayer region of preorganized organosilane bilayers. The growth of multilayers is performed by the repeated intercalation of the alkylsilane bilayers, enabling control of the number of stacked bilayers.…”

Designed synthesis of nanostructured siloxane–organic hybrids from amphiphilic silicon-based precursors

This paper reports on recent progress in the synthesis of nanostructured siloxane-organic hybrids based on the self-assembly of amphiphilic silicon-based precursors. A variety of ordered hybrid materials have been obtained by molecular design of the precursors. Alkoxysilanes and chlorosilanes with covalently attached hydrophobic organic tails are hydrolyzed to form amphiphilic molecules containing silanol groups, leading to the formation of layered (lamellar) structures. Transparent and oriented thin films of lamellar hybrids were prepared by the reaction in the presence of tetraalkoxysilane. In addition, the design of molecules having alkyl chains and large oligosiloxane heads led to the formation of mesophases consisting of cylindrical assemblies, providing a direct pathway to ordered porous silica. The synthesis, structural features, and formation processes of these hybrid mesostructures are discussed.

“…The combined use of these techniques with others, such as photolithography, allows also the organization of carbon nanotubes on a surface [15]. Furthermore, sequential self-assembly of SAM can be used to create 3D structures [3,29,30,45].…”
