General description

Benzene-1,4-dithiol (BDT) is a class of aromatic dithiol that can be used to form a self-assembled monolayer (SAM) on a variety of surfaces.

Application

BDT can be used as a cross-linker that facilitates the development of acrylate based light sensitive epoxidized soya bean oil for 3D printing applications. Gold based nanoconstrictions can be fabricated by functionalizing the surface with BDT, which reduces the overall flicker noise with respect to the unmodified surface.
This molecule can be used in single molecule junctions in electronic devices. It has also shown use in nanomaterial synthesis.

Charge transport plays an important role in defining both far-field and near-field optical response of a plasmonic nanostructure with an ultrasmall built-in nanogap. As the gap size of a gold core-shell nanomatryoshka approaches the sub-nanometer length scale, charge transport may
