Abstract: A film comprises at least one Langmuir-Blodgett layer where the layer contains or comprises an inorganic polymer containing long-chain fluoroalkyl side groups. It is distinguished by a multilayer structure having few defect points and is suitable, for example, for optical purposes and for anti-reflection surface coating. The ordering of the molecules in the multilayer can be improved by conditioning and by warming the film to above the phase transition and recooling.

Abstract: A polyurea of the general formula where X and Y are. independently of one another, a divalent radical whose chain contains in each case at least two carbon atoms, and A and B are, independently of one another, H or (C1-C26)alkyl, and n is an integer greater than 4, which polyurea contains at least one (C6-C26) alkyl group per repeating unit, is prepared by reacting the diamine NHA-X-NHB with roughly the equimolar amount of a diisocyanate OCN-Y-NCO. The polyurea is suitable for preparing ordered monomolecular LB films on a base (film-substrate-system). For this purpose it is dissolved in a volatile organic solvent which is not miscible with water, the solution is spread at the water/air interface, and the layer formed is compressed after the solvent has evaporated and it is transferred to a solid layer base by the Langmuir-Blodgett technique.

Abstract: Amphiphilic monomers with mixed-chain structures of the formula in which Y denotes -O- or -NH- X denotes a group of the formula -(CH2)n- or -(CH2-O-CH2)n- l denotes an integer from 0 to 10, n denotes an integer from 1 to 10, R1 denotes hydrogen, methyl, chlorine, cyano, fluorine or bromine, R2 denotes C1-C24-alkyl or C1-C24-fluoroalkyl and R3 denotes C8-C24-alkyl or C8-C24-fluoralkyl, with the proviso that the groups R2 and R3 contain a different number of carbon atoms. 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: New thiophene cpds. are 5-alkylthiothien-2-yl-Hg acetates and 5-alkylthio-thiophene-2-aldehyde derivs. of formula (I), where R=1-22C alkyl; X=-Hg-OCOCH3 or -CH=B; and B=a substd. C or N atom. More specifically X=-CH=C(CN)2, -CH=CH-Pyr+A-, -CH=CH-Phe-R2, -CHC=NOH or -CH=N-NH-Phe-R2; Pyr+=N-R1-substd. pyridinium-4-yl; R1=1-22, esp. 12-22C alkyl; Phe=p-phenylene; R2=a substit. more negative than H; A-=an anion; R=12-22C alkyl, esp. Me. USE/ADVANTAGE - (I) and 2-(1-22C)-alkyl-thiophene-5-aldehyde (II) are used for nonlinear optical (NLO) purposes; and some (I) are used in laminates with at least a mono-mol. layer of (I) on a substrate (claimed). These laminates can be structurised to 2D waveguides. (I), which have donor and acceptor substits., have absorption max. below 500, pref. below 450, esp. below 400 nm, high stability towards the atmos., elevated temps. and light and high NLO activity.
