Beschreibung

Allgemeine Beschreibung

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.[1][2]

Anwendung

PFOPA can functionalize gallium nitride (GaN) to tune the optical properties, which can potentially be used in chemical sensor based applications.[3] It can modify the surface characteristics of copper substrates that find usage in printed circuit boards as copper foils.[2] 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).[4][5]
