ULTRA-THIN HYDROPHOBIC AND OLEOPHOBIC LAYER, ITS METHOD OF MANUFACTURE AND USE IN CLOCKMAKING AS AN EPILAME

摘要

Ultra-thin hydrophobic layer and oleophobic layer formed by self-assembly on a solid substrate surface of an aromatic compound (I), is claimed. Ultra-thin hydrophobic layer and oleophobic layer formed by self-assembly on a solid substrate surface of an aromatic compound of formula (A-B 1) (I), is claimed. A : dihydroxy substituted aromatic compound of formula (II); Z : C or N +; X : C-H or C-L; L : electron attractor group comprising F, Cl, Br, I, CF 3, NO 2 and N(CH 3) 3 +; either Y 1H or CH3; or XY 15-6 membered heterocyclic atom; T : NH, CO, CONH or NH 2 +U 1 -; U 1 -soluble anion containing F -, Cl -, Br -, I, OH -, NO 3 -, HSO 4 -, SO 4 2-, HCO 3 - or SCN -; and B 11-20C aliphatic linear alkyl group substituted by F. An independent claim is included for a preparation of the ultra-thin layer comprising immersing the substrate in a solution containing (I) in water or its mixture and protic solvent.
