    Abstract: For the continuous production of an ultra-thin, ordered layer of amphiphilic molecules on the surface of a polar liquid, an aligned flow of the polar liquid is generated in a channel, which polar liquid contains the amphiphilic molecules, dissolved or undissolved, on the surface in spread form. In the channel, a channel section with relatively high flow rate at the surface is provided, which section has a ramp which is arranged on the channel bottom and over which the polar liquid flows. Following this there is a channel section with a relatively low flow rate at the surface, in which channel section the flow is dammed at an obstruction with the liquid level constant over time, so that an ultra-thin, ordered layer of amphiphilic molecules continuously forms, as a result of flow compression, at the polar liquid/air phase boundary in these channel sections. The ramp over which the liquid flows is arranged so as to be movable.

    Abstract: 23221-4583 of the disclosure 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 in which R1 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.

    Abstract: HOE 91/F 380 Measuring system for the determination of the concentration of inorganic and organic compounds in a sample Measuring system for the determination of the concentrations of inorganic and organic compounds in a sample, having a sensor to be brought into contact with the sample, which sensor contains an optical fluorescent indicator which, upon excitation via an excitation light source, fluoresces as a function of the present concentration of the inorganic or organic compound to be detected. The measuring system is configured for measuring and evaluating the incoming radiation and the reemitted fluorescent light. The measuring system comprises a sensor element to be brought into contact with the sample, said sensor element being composed of a polymer matrix which is prepared from a) a matrix component derived from one or more units of the formula I in which (I) R1- is hydrogen, deuterium or methyl; R2- and R3-, independently of one another, are hydrogen, deuterium or methyl, and the degree of polymerization n is an integer in the range from 80 to 2500, preferably from 200 to 2000; - - HOE 91/F 380 b) a dye component which is immobilized covalently on the acyl chloride groups of the matrix component, and c) one or more swelling components which are bound covalently at the remaining free acyl chloride groups of the matrix component.
