Descripción general

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

Aplicación

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

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

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold.
