Abstract
Zirconium- and hafinium-alkyldiylbisphosphonate multilayer films are p repared on modified gold and silicon substrates. The substrates are fu nctionalized via 3-(hydroxydimethylsilyl) propanephosphonic acid and m ercapto-3-butylphosphonic acid to yield a phosphonic acid surface. Mon o- and multilayer films are then prepared by alternatively adsorbing m etals such as Zr4+ and Hf4+, and alpha, omega-bis(phosphonic acids) fr om the aqueous solution. The characteristics of multilayer films were characterized by ellipsometry, x-ray reflectometry, AFM and surface pl asmon resonance measurement.
