Abstract: A group of novel, low temperature liquid crystalline compounds with terminal, primary or secondary amino polar electron donating groups are disclosed. These include, for example, p-alkyl-or alkoxy-phenylcyclohexanes, bicyclohexyls or biphenyl ring systems, substituted at the p' position with alkyl primary or secondary amines, of which one example is p-(4-trans-n-pentylcyclohexyl)benzylamine.

Abstract: A method of making and using a liquid crystal cumulative dosimeter container including a resilient outer body sealed to confine a first liquid crystal composition constituent and a second liquid crystal composition constituent and having at least one transparent section to permit observation of the color of the confined composition, and a barrier contained completely within and physically unattached to the outer body for separating the first constituent from the second constituent, whereby disruption of the barrier allows the first constituent to mix with the seocnd constituent. The barrier is formed either by encapsulating one or both of the constituents or by using air bubbles.

Abstract: Irradiation of collected S.sub.4 N.sub.4 decomposition products with light or radiation in the .gamma. to visible range enhances the initiation of polymerization of the decomposition products to produce polysulfur nitride, which is typically conductive and usually referred to as (SN).sub.x. Irradiation of a masked coating of collected S.sub.4 N.sub.4 decomposition products and completion of polymerization thereof and removal of non-irradiated, non-polymerized portions thereof will result in an electrically conductive coating disposed in a preselected pattern. S.sub.4 N.sub.4 decomposition products may also be dispersed in a matrix, e.g. a photographic emulsion which is transparent or partially transparent to light, or which may be rendered partially or selectively transparent or opaque. This might be useful, for example, for imaging applications, or for producing a selectively transparent pattern for subsequent photoinduced initiation of polymerization of the S.sub.4 N.sub.4 products.

Abstract: Liquid crystal mixtutre of donor and acceptor molecules, the first consisting of a liquid crystal compound having an unshared electron pair (the donor) and the second generally consisting of an electron receptive compound such as a p-cyano-p'-alkyl- or alkoxy-substituted bipheny liquid crystal compound (the acceptor); together these compounds form a molecular complex with improved physical properties, including particularly a broader mesophasic temperature range, then would be expected from a simple combination of such liquid crystals.

Abstract: Using a standardized cell containing a thin layer of an aligned nematic liquid crystalline material, a relationship is determined between concentration of an optically active solute material in the liquid crystal layer and line spacing in a pattern produced by differential light refraction, upon the injection of different amounts of the optically active compound. Subsequently, quantitative analysis of a sample containing the optically active compound is accomplished by injecting a known amount of the sample into a second identical standardized cell, observing the line spacing of refracted light in the second cell and comparing it to the relationship determined in the first cell. Optically active compounds analyzable in this manner include steroids and cholesteryl esters. A preferred nematic liquid crystalline material is n-p-methoxybenzylidene-p-n-butylaniline. A specific system described consists of cholesteryl-2-methyl valerate in homeotropically aligned n-p-methoxybenzylidene-p-n butylaniline with a layer thickness in the cell of 12.7 microns.

Abstract: Nematic liquid crystal compositions including a relatively small amount of a charge-transfer acceptor dopant exhibit substantially different voltage-transmission characteristics in dynamic scattering as compared to undoped nematic liquids. Nematic compositions based on azoxy compounds and dopants of the cyano or halo tetra substituted quinone types are preferred.
