FILM COMPOSED OF AT LEAST ONE MONOMOLECULAR LAYER

摘要

A film for use in non-linear optics is composed of at least one Langmuir-Blodgett film, the film containing a dye of the formula …… in which R<1> is a long-chain alkoxy, acyloxy, alkylamino or acylamino group, or is composed of this dye. The film, especially if it contains alternating layers of unsaturated amphiphilic compounds, produces a stable multilayer having good non-linear optical properties and is suitable, for example, for electrooptical switches, diode/laser frequency amplifiers or optical parametric amplifiers. …In addition to the dye mentioned, the monomolecular film can contain at least one other second amphiphilic compound, in which case the monomolecular film is composed of amphiphilic compounds.
