Abstract. p-A - diagrams, ellipsometry and contact potential difference measurements were used to study the preparation and surface potential of calixarenes LBFs modified with phosphorylated groups at upper molecular rim (see text). The Langmuir nature of the obtained films on the silicon substrates has been proved. The surface potentials and molecular concentrations have been measured for all the compounds under investigation. Normal components of the dipole moments were analyzed for observed calixarenes. In monolayered structures they appeared to be positive for the molecules as a whole as well as for their parts.

Keywords: Langmuir-Blodgett films, calixarene, dipole moments.
