    摘要： An optical component comprises an electromagnetic radiation-transparent polymeric medium having a second-order susceptibility of at least 10.sup.-9 electrostatic units where this polymeric medium comprises compounds having polar-aligned noncentrosymmetric molecular dipoles which have as structural element an electron acceptor which is bound to an electron donor via a conjugated .pi.-electron system, which makes possible an oscillation of the molecular dipole between a ground state having a first dipole moment and an electronically excited state having a second dipole moment different from the first, and the nonionic polymeric medium comprises an alternating arrangement of at least one Langmuir-Blodgett film each of at least two different nonionic polymers having nonlinear optical properties. Besides high mechanical and chemical stability the optical component of the invention has excellent nonlinear optical properties, for example frequency-doubling.

    摘要： In order to continuously produce an ultrathin, ordered layer of amphiphilic molecules on the surface of a polar liquid a directed flow of the polar liquid is produced in a duct which contains the amphiphilic molecules in dissolved or undissolved form on the surface in spread form. In the duct, a duct section having a relatively high flow rate on the surface and comprising a ramp which is arranged at the bottom of the duct and washed over by the polar liquid is provided. This is followed by a duct section having a relatively low flow rate on the surface, in which the flow is dammed up at an obstacle at a liquid level constant with time, so that an ultrathin, ordered layer of amphiphilic molecules is continuously formed in these duct sections at the polar liquid/air interface by compression of the flow. The washed over ramp is movable.

    摘要： Polyamides of the general formula [N(A)-X-N(B)-CO-Y-CO-].sub.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 C.sub.1 to C.sub.26 alkyl group and n denotes an integer greater than 4. The said polyamides contain at least one alkyl group of C.sub.6 to C.sub.26 per repeating unit. The groups X and/or Y contain at leat one CH.sub.2 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.
