Sulphoxides and secondary products

摘要

The invention relates to novel sulphoxides of the formula <IMAGE> 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 <IMAGE> . The poly(arylenevinylene) compounds are suitable, for example, as photoluminescent or electroluminescent material.
