ORGANIC INORGANIC LANGMUIR-BLODGETT-FILMS BASED ON METAL PHOSPHONATES2 - ZIRCONIUM PHOSPHONATE-BASED ALTERNATING LAYER FILMS/

Langmuir-Blodgett (LB) films of zirconium salts of the functionalized phosphonic acids 4-octadecyloxyphenylphosphonic acid (P0), 4-octadecyl oxybiphenylphosphonic acid (B0), and 4-(4-octadecyloxyphenyldiazenyl)p henylphosphonic acid (A0) have been prepared and characterized. Layers of P0, B0, or A0 can be deposited onto zirconated octadecylphosphonic acid layers using a three-step deposition procedure to form alternati ng zirconium phosphonate LB bilayers. Film composition and molecular o rientations are characterized through X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and Fourier transform infrared spectr oscopy (FTIR).
