| titleOfInvention | METHOD FOR PRODUCING THIN LAYERS |
| abstract | Prodn. of a thin layer of amphiphilic cpd(s) (I) on a substrate (II) is by producing, in a horizontal channel, an oriented stream of polar liq. (III) contg. mols. of (I) in soln. or spread on the surface, blocking the stream with a horizontal barrier at the fluid/(III) interface and opt. choosing a concn. of (I) such that a compressed layer of (I) is continually formed at the interface in front of the barrier, then moving the substrate (II) through this zone of compression; the novelty is that (I) are polyamides, pref. poly-glutamates. A thin layer of (I) contg. a lipophilic dye (IV) is produced in the same way, by adding a soln. of (IV) in an organic solvent which is immiscible with water. A monomol. layer of (I) and (IV) on a water surface is claimed; this monolayer is produced by process 1 (b) and has a dichroic ratio above 1.0, pref. above 2.0. (I) are polycondensates of different gamma-alkyl-substd. copolyglutamates, pref. copolycondensates of gamma-alkyl-L-glutamate and gamma-alkyl'-L-glutamate (with alkyl = 1-6C alkyl and alkyl' = 12-36C alkyl), esp. pref. gamma-methyl- and gamma-octadecyl-L-glutamate; (IV) has approx. rod-shaped mols., and is pref. a diazo dye, a cyanine or a carotenoid. |
