Abstract: The invention relates to particle-shaped, line-shaped, planiform or three dimensional entities comprising, at least on the surface thereof, a hydrophilically effective amount of at least one polymer containing urethane and/or urea groups in addition to ammonium groups. The ammonium groups are obtained by quaternizing or neutralizing tertiary amino groups, preferably with carbonic acid.

Abstract: The novel compounds of the general formula I having nonlinear optical properties in which the variables have the following meaning: X is a straight-chain or branched alkanediyl radical having 1 to 20 C atoms or X is a straight-chain or branched alkanediyl radical having 2 to 20 C atoms, the carbon chain of which is interrupted by -O-, -S- and/or -NR-; R is a hydrogen atom, a straight-chain or branched alkyl radical having 1 to 6 C atoms or a cycloalkyl radical, Y is a non-centrosymmetrical radical containing an easily polarisable conjugated pi -electron system and at least one terminal electron acceptor group; are outstandingly suitable as nonlinear optical materials for nonlinear optical arrangements and for the preparation of polymers having nonlinear optical properties. In particular, they are used for the preparation of organopolysiloxanes having nonlinear optical properties and which contain side groups of the general formula Ia in which the variables have the abovementioned meaning. These novel organopolysiloxanes having nonlinear optical properties are in turn outstandingly suitable for the preparation of Langmuir-Blodgett films.

Abstract: The present invention relates to particulate, linear, sheet-like, or three-dimensional structures which comprise, at least on their surface, a hydrophilicizing amount of at least one polymer which has urethane groups and/or urea groups, and also ammonium groups. The ammonium groups are obtained by quaternizing or neutralizing tertiary amino groups, preferably with carbonic acid.

Abstract: The method for chemically differential imaging using a scanning force microscope uses chemically modified samples, where the imaging is in normal force, elasticity or tapping/non-contact mode. A detector (1), laser source (2), piezoelectric adjuster (3), tip and lever arm (4) are used to evaluate the sample (5). The scanning tip is either a metal or oxide layer, or it may be coated with one or more substances, such as thiol groups with additional acid or base functions, thiol with nuclein base, disulphide with acid base or nuclein base.

Abstract: The invention relates to a miniaturisable, capacitively measuring chemical sensor system on a semiconductor basis, comprising a sensor and a reference element which are to be contacted with the electrolyte to be measured, the reference element being connected in series with the sensor, the reference element comprising a highly doped semiconductor substrate or metal/semiconductor substrate which is coated with a membrane, and the sensor comprising an insulator/semiconductor substrate which is coated with a sensitive membrane, and the sensitive membrane of the sensor being more sensitive than that of the reference element. Sensor and reference element of said sensor system can either be applied to the same chip or consist of individual components which can readily be interchanged.

Abstract: The invention relates to disulphides of the general formula X -(CH2)n-S-S-(CH2)n-X in which X and X are identical to one another and represent -Br, -N-phthalimide, -NH2, -OOC-(CH2)3-COOH, -O-SO2-CH3, -NH-(CH2)2- NH2, -SO3H or -SO3 M where M = an alkali metal ion, and n = 11 to 25, or X represents -OH and X represents -Br or X and X represent -COO-CH2-CH3 and n = 10 to 25, and to a process for their preparation. These disulphides are suitable for the preparation of monomolecular layers on noble metal supports and for the building up of multimolecular layers.
