Abstract: The invention relates to compounds of the formula in which R and R are halogen atoms and/or Me S groups, where R and R may be identical or different, X is hydrogen, chlorine and/or bromine, Y is sulphoxide, -SO-, and/or sulphone, -SO2-, m is an integer from 2 to 500, n is zero or an integer from 1 to 450, where n + m can be at most 500, with the proviso that the halogen content (from R or R and X) of the compound makes up at least 10 % by weight. These compounds are prepared by reacting compounds of the formula in which R and R are halogen atoms and/or Me S groups, where R and R may be identical or different, X is hydrogen and m is an integer from 2 to 500, with chlorine or bromine in an inert organic solvent or in an aluminium chloride melt, which may contain additives, at elevated temperatures. The compounds of the formula I are used for flameproofing thermoplastics.

Abstract: The invention relates to a process for the preparation of electrically conductive polyaromatics; in which the polyaromatics are treated with 0.5 to 5% by weight of a strong Lewis acid having pks values from -10 to +4, with the exclusion of aqueous moisture and of oxygen, and in which the polyaromatics used are compounds having conjugated pi -systems in which at least two polyene chains of the formula (I) and (II): in which n = 1 to 100 and m = 0 to 50 run in parallel. Suitable polyaromatics are quarterylene, quinquerylene, sesquicylene or dianthracene. The electrically conductive polyaromatics can be used in electrical engineering for the production of solar cells, for the conversion and fixation of radiation, for the preparation of electrical and magnetic switches and electrical memories and for the antistatic finishing of plastics.

Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are dark in color, possess substantially panchromatic absorption characteristics, and are of the general formula where R1 is propyl, 1-hydroxypropyl, 1-methoxypropyl or 1-phenylethyl, Z is p-phenylazoanilino, phenylthio or anilino, and n is 0-6, and a process for the production of this electrophotographic recording medium.

Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are those of the general formula I I where R1, R2, R3 and R4 are each hydrogen or a non-ionic substituent, X and Y are each the radical of a methylene-active compound, or of an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic amine or hydrazine, and Z is hydrogen, methyl or phenyl, and the production of this recording medium.
