Ring-Closing Metathesis and Nanoparticle Formation Based on Diallyldithiocarbamate Complexes of Gold(I): Synthetic, Structural, and Computational Studies

“…The reduction of well-defined gold(I) precursors containing phosphine, amine, , alkyl, carboxylate, and, most recently, carbene ligands has been shown to yield ligand-stabilized gold nanoparticles. Direct routes to thiolate-capped gold nanoparticles have also been reported from gold(I) thiolate precursors, which are often polymeric or cyclic in nature. − c This approach has been extended to patterning using e-beam lithography/thermolysis protocols. , Recently, the thermal preparation (140 °C) of thiol-coated gold nanoparticles was reported from molecular methylgold(I) precursors in the presence of thiol surfactants .…”

A novel approach to fingerprint visualization on paper using nanotechnology: reversing the appearance by tailoring the gold nanoparticles' capping ligands

“…In fact, several AuNPs which are capped with mercaptocarboxylic acids have been described in the literature and fully characterized. [10][11][12] AuNPs capped with the following list of mercaptocarboxylic acids have been prepared and tested (Fig. 2).…”

Bifunctional Chalcogen Linkers for the Stepwise Generation of Multimetallic Assemblies and Functionalized Nanoparticles

“…Ligand-stabilized gold nanoparticles can also be obtained through the reduction of well-defined gold­(I) precursors containing phosphine, amine, alkyl, carboxylate, and carbene ligands. Given their ready thermal reduction in the gilding process of ceramics, it is not surprising that gold­(I) thiolate precursors (often polymeric or cyclic species) have also been employed in the direct preparation of thiolate-capped gold nanoparticles. − This approach has been further developed using e-beam lithography/thermolysis protocols. , Thermolysis of monometallic gold­(I) dithiolate complexes has been used to generate gold nanoparticles stabilized by alkyl groups, while molecular methylgold­(I) precursors have been employed in the presence of thiol surfactants to prepare thiolate-protected gold nanoparticles by a thermal route (140 °C) . We have recently reported that the metallacyclic digold complexes [Au 2 (S 2 CNR 2 ) 2 ] (NR 2 = N­(CH 2 CHCH 2 ) 2 , NC 4 H 6 ) undergo reduction to form gold nanoparticles with diameters of 4.0 or 4.8 nm (±0.7 nm).…”
