Abstract: The invention relates to photoconductors having liquid-crystalline properties made from low-molecular-weight or polymeric organic compounds, where the photoconduction in the discotic phase is greater than in the non-liquid-crystalline phases, and to a process for increasing the photoconductivity by molecular ordering in photoconductors.

Abstract: The invention relates to positive-working, radiation-sensitive mixtures essentially comprising (a1) an organic binder containing acid-labile groups which is insoluble in water, but becomes soluble in aqueous alkaline solutions on treatment with acid, or (a2.1) a polymeric binder which is insoluble in water, but soluble in aqueous alkaline solutions and (a2.2) an organic compound whose solubility in an aqueous alkaline developer is increased by treatment with acid, and (b) an organic compound which produces an acid on exposure to actinic radiation and which additionally contain (c) a strongly basic, organic compound containing hydroxyl, alkoxy or phenoxy anions. These mixtures are suitable for the production of relief structures of improved contrast.

Abstract: Positive-working radiation-sensitive mixt. is based on (a) polymer(s) contg. acid-labile gps., which are insol. in water and rendered soluble in aq. alkaline soln. by acid; (b) organic photo-acid(s); and (c) other organic cpd(s)., in which (a) comprises 35-70 mole-% 4-hydroxystyrene units (I), 30-50 mole-% 4-tetrahydropyran-2-yloxystyrene units (II) and 0-15 mole-% 4-vinylcyclohexanol units (III); (b) is 2-methyl-4-hydroxy-5-isopropyl-phenyl-dimethylsulphonium triflate (IV); and (c) is an organic ammonium deriv. (V) of (IV) or an analogue. In the formulae, R', R", R'" = 1-4 C alkyl; or R', R" = CH2 gps. linked to a 5-membered ring.

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 invention relates to the preparation of pure triethylenediamine (TEDA) by evaporating TEDA from the mixture comprising a solvent or diluent, where the solvent or diluent has a boiling point at atmospheric pressure in the range from 175 to 250° C., passing the vapor-form TEDA into a liquid solvent, and subsequently crystallizing the TEDA out of the resultant solution.

Abstract: The invention relates to an electroluminescent arrangement, comprising one or more organic layers, characterized in that at least one of the layers is obtained by thermal or radiation-induced crosslinking, and in that each layer contains at least one charge-transporting connection (compound). The arrangements according to the invention are, for example, very suitable for the production of displays.
