Phosphonic Acids
Alcylphosphonic acids are perfect hydrophobization ligands, owing to their classical bifunctional chemical structure. They contain an unpolar organic hydrophobic alkyl chain and an active hydrophilic phosphonic acid group. These molecules are capable to strongly bind to the surface of different inorganic materials (SiO2, Al2O3, TiO2, FexOy, ZrO2, ZnS etc.) forming a selfassembled coating layer.

Phosphonic acids can also be used as ligands for the synthesis of nanoparticles to control the size and hydrophobic properties of the particles.

Phosphonic acids are well soluble in non-polar and many polar solvents. They are also soluble in water (especially upon addition of alkali) at lower concentrations.
