“…PDMS prepolymer (Sylgard 184 silicone elastomer) and PDMS curing agent (Sylgard silicone elastomer curing agent) were purchased from Dow Corning Corporation. Synthesis and purification of thioether-modified calix [4]arene 1 [12], thioethermodified cavitand 2 [12], tris-thioether 3 [13], and didecylsulfide 4 [14] have been described elsewhere.…”

Thioether derivatives with 1–4 thioether moieties were used as inks in microcontact printing on gold for the reproduction of patterns as they combine good monolayer quality with synthetic versatility, and high molecular weights. Self‐assembled monolayers (SAMs) on gold of compounds 1 and 2 had a quality comparable to SAMs of decanethiol, both regarding monolayer order and etch resistance. Etch resistances of SAMs of 3 and 4 were lower. Resulting structures after etching of patterned SAMs using 1, 2, and 3 were of good quality for patterns with feature sizes on the same stamp ranging from 1–200 μm. Patterns of 4 were not reproduced. Overall, compounds 1 and 2 are good candidates for low‐diffusion inks.

“…[77] So far, only a few studies investigating the stability of the gold-sulfide bond have been reported. [78,79] Dialkyl sulfide stabilized gold nanoparticles displayed reversible exchange already at about 50 8C. However, the multiple binding sites of the heptameric ligands 1-4 are expected to provide nanoparticles with increased stabilities due to kinetic stabilization.…”

Aiming at the formation of inorganic/organic hybrid gold nanoparticle superstructures, the design and synthesis of acetylene‐monofunctionalized multidentate thioether ligands and their ability to stabilize gold nanoparticles are presented. Rather monodisperse gold particles with diameters of about 1 nm are obtained, which are coated by a small number of ligands, each comprising a silyl‐protected acetylene. The acetylene is attached at the end of a rigid ethynylene‐phenylene unit of variable length, leading to functionalized gold nanoparticles carrying acetylenes at different distances from the nanoparticle surface. These particles are interlinked by diacetylene formation and are investigated by transmission electron microscopy and UV/vis spectroscopy, revealing the formation of nanoparticle aggregates and small superstructures such as dimers or trimers while the nanoparticles themselves retain their integrity. The interparticle distance in small nanoparticle superstructures reflects the ethynylene‐phenylene spacer length corroborating the wet chemical interlinking as the origin of these organic/inorganic hybrid structures.

“…8,9 Therefore, M n of D3OTP obtained from GPC calibrated with linear polystyrene standards might be lower than true molecular weight of D3OTP. Since the sulfide group (-CH 2 -S-CH 2 -) which is located in the hydrophilic core region of D3OTP has an affinity to gold, 10 Figure 1. The relatively sharp peaks from the α-protons of D3OTP at around 2.7 ppm changed to two new broad peaks shown at around 2.8 and 3.3 ppm when the gold salt is complexed.…”

We synthesized gold nanonetwork using the amphiphilic polymer brush, poly(oxyethylene) containing decyltri(oxyethylene)thiomethyl (C 1 0 H 2 1 (OCH 2 CH 2 ) 3 SCH 2 -) side groups, as a stabilizer and/or a template. When tetrabutylammonium borohydride solution in THF was added to a mixture solution of the polymer and LiAuCl 4 in THF, 0-D gold nanomaterials were obtained. However, when an aqueous solution of sodium borohydride was added, gold nanonetworks were synthesized. The composites composed of polymer/0-D gold nanomaterials and polymer/ gold nanonetworks showed electrical conductivities of ~10 -9 and ~10 -3S/cm, respectively, which indicated that the gold nanonetworks increased the electrical conductivity.
