Biphenyl-4,4'-dithiol Chemical Properties, Uses, Production

Uses

BPDT can be used to functionalize iron nanoparticles (NPs) with the gold shell (FeAu) on polyethylene substrate. It can also be coated on the p-doped gallium arsenic (GaAs) substrate for a variety of semiconductor applications.

Definition

ChEBI: Biphenyl-4,4'-dithiol is a dithiol and a member of biphenyls.

General Description

Biphenyl-4,4′-dithiol (BPDT) is an aryl dithiol that is prepared by taking a mixture of stannous chloride dihydrate and glacial acetic acid with anhydrous hydrogen chloride. It forms a self-assembled monolayer on a variety of surfaces by attaching one thiol group to the surface while the other can create nucleation sites for other functional groups.
