| 摘要 |
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, CF3, NO2 and N(CH3)3+, Y represents H or CH5, or Y forms a 5- or 6-atom heterocycle with X, T represents NH, CO, CONH or NH2+U−, U− being a soluble anion, 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 a harrier film.
