Abstract: This invention concerns an electroluminescent device, the electroluminescence spectrum of which does not overlap with the absorption spectrum, which contains two or more organic layers between two electrodes. This device is characterized by the fact that a) two neighboring organic layers each have an optical band gap of at least 2.5 eV, and b) the wave length ( lambda max corresponding to an energy Emax), at which the electroluminescence reaches a maximum, lies in the range which corresponds to the energy difference DELTA E (ionization potential of the first organic layer minus electron affinity of the second organic layer), Emax being less than or equal to 2.5 eV.

Abstract: The invention concerns the use in electroluminescent devices of heterospiro-compounds of formula (I), in which PSI means an element of the fourth main group of the periodic system of elements, with the exception of carbon, and is preferably Sn, Ge or Si, particularly preferably Ge or Si, and K and K , independently of each other, mean conjugated systems. The compounds of formula (I) are distinguished by good solubility in common organic solvents, improved film-forming properties and a considerably reduced tendency towards crystallization.

Abstract: Polyamides of the general formula [N(A)-X-N(B)-CO-Y-CO-]n are described, in which Y denotes a divalent group, X a divalent radical whose chain contains at least two carbon atoms, A and B independently of one another denote H or a C1 to C26 alkyl group and n denotes an integer greater than 4. The said polyamides contain at least one alkyl group of C6 to C26 per repeating unit. The groups X and/or Y contain at leat one CH2 group in the chain. The polyamides are prepared by reaction of a diamine of the formula NHA-X-NHB with an about equimolar amount of a reactive derivative of a dicarboxylic acid of the formula COOH-Y-COOH. The polyamides obtained can be used in order to prepare highly ordered monomolecular LB films on a support. For this purpose, the polyamide is dissolved in a volatile organic solvent which is immiscible with water and the solution is spread on the water/air interface. After evaporation of the solvent the layer is compressed and transferred to a solid support by the LB technique. The film is very stable and can be used to prepare optical waveguide systems, filters for optical purposes or protective layers.

The monomers are polymerized on their own or together with other comonomers. The polymers obtained are suitable for the preparation of ultra-thin layers on a suitable layer support.

Abstract: 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 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.

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.
