General description

1H,1H,2H,2H-Perfluorooctanephosphonic (PFOPA) acid is a fluoroalkyl phosphonic acid that contains 8 fluorinated carbon atoms. It forms a self-assembled layer on the substrate due to the adhesion of the phosphonates. The surface adhesion is a component of the acid base linkage that is enhanced by the hydroxyl groups.

Application

PFOPA can functionalize gallium nitride (GaN) to tune the optical properties, which can potentially be used in chemical sensor based applications. It can modify the surface characteristics of copper substrates that find usage in printed circuit boards as copper foils. PFOPA can also be coated on the indium tin oxide substrate, which may be utilized in organic light emitting diodes (OLEDs) and organic photovoltaics (OPVs).
