A film for use in nonlinear optics comprises at least one Langmuir-Blodgett layer, the layer containing or comprising a dye of the formula ##STR1## in which R.sup.1 denotes a long-chain alkoxy, acyloxy, alkylamino or acylamino group. In particular when the film contains alternating layers of unsaturated amphiphilic compounds, it produces a stable multilayer having good nonlinear optical properties and is suitable, for example, for electrooptical switches, diode laser frequency amplifiers or optical parametric amplifiers. Besides the dye indicated, the unimolecular layer can additionally contain at least one second amphiphilic compound. In this case, the unimolecular layer comprises amphiphilic compounds.
