Description

General description

12-Mercaptododecylphosphonic acid (MDPA) is an organophosphonic acid that forms a self-assembled monolayer (SAM). The phosphonic groups tend to react with the metal surfaces that allow the formation of metal-oxygen-phosphonate (M-O-P) bonds that facilitate the surface with mechanical and chemical stability.[1]

Application

MDPA based SAM can be coated on TiO₂ for potential applications in the extraction of heavy metals.[2] It can also be used in surface modification of a graphene oxide (GO) based active material for the fabrication of a organic field effect transistor (OFET).[3]

Organophosphonic acid self-assembled monolayers (SAMs) for nanoelectronics; solid-state lighting; energy generation and nanocomposites. A mercaptoalkylphosphonate monolayer used to bind gold nanoparticles.
