Abstract: Film comprising at least one unimolecular layer. 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 monlinear 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.
Abstract translation: 包含至少一个单分子层的膜。 用于非线性光学的膜包括至少一个Langmuir-Blodgett层,该层包含或包含式“IMAGE”的染料,其中R1表示长链烷氧基,酰氧基,烷基氨基或酰基氨基。 特别是当膜含有不饱和两亲性化合物的交替层时,它产生具有良好的单线性光学特性的稳定的多层膜,并且适用于例如电光开关,二极管激光器放大器或光学参数放大器。 除了所示的染料之外,单分子层还可以含有至少一种第二两亲性化合物。 在这种情况下,单分子层包含两亲性化合物。
