General description

1,4-Benzenedimethanethiol forms self-assembled monolayers on gold in n-hexane solution.

Application

1,4-Benzenedimethanethiol was used as cross linker in the fabrication of nanoporous gold on glassy carbon electrode by alternatively assembling gold nanoparticles and silver nanoparticles. It was used as capping reagent during the preparation of Au and Ag clusters of 3 nm mean diameter. It was used as ligand in the synthesis of 1,4-benzenedimethanethiol-capped gold nanoparticles.

Au and Ag clusters of 3-nm mean diameter were prepared with 1,4-benzenedimethanethiol (BDMT) as the capping molecule. In both the monolayer-capped clusters, BDMT adsorbs in the dithiolate form in contrast to in the 2D monolayers, where the dithiolate form exists

Nanoporous gold (NPG) has recently received considerable attention in analytical electrochemistry because of its good conductivity and large specific surface area. A facile layer-by-layer assembly technique fabricated NPG was used to construct an electrochemical immunosensor for carcinoembryonic antigen (CEA). NPG

Stable gold nanoparticles stabilized by different mono and bi-functional arenethiols, namely, benzylthiol and 1,4-benzenedimethanethiol, have been prepared by using a modified Brust's two-phase synthesis. The size, shape, and crystalline structure of the gold nanoparticles have been determined by high-resolution electron

Nematic liquid crystal elastomers (N-LCE) exhibit intriguing mechanical properties, such as reversible actuation and soft elasticity, which manifests as a wide plateau of low nearly-constant stress upon stretching. N-LCE also have a characteristically slow stress relaxation, which sometimes prevents their
