Abstract text


The invention relates to a novel ultra-thin hydrophobic and oleophobic layer, formed by self-assembly on a solid substrate surface, of compounds of the general formula


A-B

in which
A represents a group of the formula

    • in which
      • Z represents C or N+,
      • X represents C—H or C-L, L being an electron-attracting group selected from F, Cl, Br, I, CF3, NO2 and N(CH3)3+,
      • Y represents H or CH3, or Y forms a 5- or 6-atom heterocycle with X,
      • T represents NH, CO, CONH or NH2+U−, U− being a soluble anion such as e.g. F−, Cl−, Br−, I, OH−, NO3−, HSO4−, SO42−, CO32−, HCO3− or SCN−, and B represents a C1-C20 linear aliphatic alkyl group partially or completely substituted with F,
        and a method of preparing this layer and its use as an epilame.
