Abstract: Transistor has parallel planar source and drain electrodes (1, 2) which are 0.01-100 mu m apart, gate electrode(s) (3) which have the same dimensions as the source and drain electrodes and are placed parallel to and between them, and a layer (4) of discotic columnar liquid crystalline material (I) between the source and drain electrodes with the columnar axis oriented perpendicular to the surface of these electrodes. Also claimed is electronic or electro-optical equipment contg. this transistor.

Abstract: The use of organic material (I) with a specific conductivity ≤ 10 S/cm and a nonionic charge carried mobility of >10 cm /Vs as charge transport medium is claimed, with the proviso that light absorption by (I) does not cause an increase in the charge carrier concn. by a factor of 10 or more. Also claimed are electrochemical cells contg. organic charge transport medium as electrolyte.

Abstract: Compounds have the general formula (I) Z[-Y -(A-Y )m-X]n, in which the variables have the following meanings: Z stands for an n-valent aliphatic residue with 2 to 20 C atoms or for an n-valent three to seven-membered saturated or unsaturated carbocyclic or heterocyclic residue that may also be benzocyclised, or for an n-valent siloxane or cyclosiloxane residue with up to 10 Si atoms; Y , Y stand for a chemical bond, oxygen, sulphur or a group -CO-O-, -O-CO-, -N(R)-CO- or -CO-N(R)-; m equals 0 or 1; A stands for an alkylene group with 2 to 20 C atoms in which non-adjacent C atoms may be substituted by oxygen, sulphur, -CO-O-, -O-CO- or -N(R)-; n equals 2 to 6; R stands for hydrogen or C1-C4-alkyl; and X stands for a substituted triphenylene residue. Because they recur n times in the compounds, A, Y , Y , m and X may be the same or different. These compounds are useful as charge carriers.

Abstract: Methacrylate (co)polymers containing carbazolyl side groups contain or are composed of repeating units of the general formula (I) (I) where m is an integer of from 3 to 11. The novel methacrylate (co)polymers containing carbazolyl side groups can advantageously be used as photoconductors in photoconductive layers, in particular of electrophotographic recording elements.
