Description

General description

(12-Phosphonododecyl)phosphonic acid (PDDPA) is a phosphonic acid derivate that forms a self-assembled monolayer (SAM) on a variety of nanoparticle surfaces. The phosphonate groups interact with the hydroxyl groups of the nanoparticles to form stable interfacial linkages.

Application

PDDPA can be used to functionalize zinc nanoparticles which may be used to modify the work function for solar cell (SC) based applications. It can also modify the surface of titanium by fabricating biomimetic calcium-phosphate layers which can be used in the surface treatment of dental implants.

SAMs on metal oxide surfaces. Preparation of organophosphonate multilayers on silicon and gold surfaces.
