Abstract: The invention relates to novel sulphoxides of the formula in which Ar is an optionally substituted aromatic carboxylic radical, the radicals R are, independently of one another, hydrogen, C1- to C4-alkyl or optionally substituted phenyl, and radicals X are, independently of one another, radicals bonded via hydrogen-free carbon atoms, which are suitable for the preparation of poly(arylenevinylene) compounds and which can be converted into the polymers via prepolymers of the formula . The poly(arylenevinylene) compounds are suitable, for example, as photoluminescent or electroluminescent material.

Abstract: The invention relates to a radiation-sensitive mixture essentially comprising (a) a water-insoluble binder or binder mixture, and (b) a compound which forms a strong acid on irradiation, where component (a) is a phenolic resin all or some of whose phenolic hydroxyl groups have been replaced by groups (IA) or (IB) in which R , R and R are alkyl radicals, or R together with R forms a ring, and X is CH2, O, S, SO2 or NR . This radiation-sensitive mixture is suitable for the production of relief structures.

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 polymeric discotic liquid-crystalline charge transfer complexes comprise A) at least one polymer which contains groups in chemically bound form which a1) do not form a liquid-crystalline phase by themselves, a2) form a calamitic liquid-crystalline phase by themselves or which a3) form a discotic liquid-crystalline phase by themselves, and B) at least one low-molecular-weight compound or a polymer having electron-acceptor or electron-donor action; the preparation of these novel complexes and a novel process for the preparation of single-phase liquid-crystalline polymer blends of polymers which are otherwise completely or substantially incompatible with one another, which leads to the formation of the novel complexes, are also described.
