Due to their affinity for a wide range of substrates, organophosphorus acids are increasingly used as coupling molecules to anchor organic groups to inorganic surfaces,[1-6] for applications in the fields of heterogeneous catalysis, lubrification, corrosion resistance, biomaterials, etc.
Here, we wish to present recent results on the kinetics of deposition of phosphonic acid self-assembled monolayers, followed by in situ ATR-FTIR (Fig. 1) and on the bonding mode of phosphonate units in titania/phosphonate hybrids and SAMs studied by high-field (17 T) 17O MAS-NMR, in collaboration with C. Gervais (Paris) and D. Massiot (Orleans) (Fig. 2). In addition, we wish to illustrate the possibilities offered by organophosphorus coupling molecules by several examples:
- selective surface modification of patterned SiO2-TiO2 supports and mixed oxides
- phosphonate monolayers on titanium and stainless steel for biomaterials.
