General description

p-Terphenyl-4,4″ -dithiol (TPDT) is an alkanethiol that forms a self-assembled monolayer (SAM) on a variety of substrates. It can be used to form a dithiol ligand that functionalizes and modifies the properties of surfaces.

Application

TPDT forms a SAM on gold nanoparticle by immobilizing the surface atoms, which can be used in opto-electronic and other energy based applications.
