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.

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).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
