Abstract

A process for the preparation of electrically conductive heteropolyphenylenes, wherein from 0.5 to 5 per cent by weight of an activating additive is introduced, in the absence of moisture and of oxygen, into a heteropolyphenylene of the general formula ##STR1## where X is O, S, Se, SO or SO.sub.2 and Y has one of the meanings given for X or is NH, CH.sub.2, CO or C.sub.6 H.sub.4, and n is from 2 to 250. The activating additive is preferably one of the compounds AsF.sub.5, SbF.sub.5, UF.sub.6, HClO.sub.4, NO.sup.+ SbF.sub.6.sup.-, NO.sub.2.sup.+ SbF.sub.6.sup.-, NO.sup.+ PF.sub.6.sup.-, SbCl.sub.5, NO.sub.2.sup.+ PF.sub.6.sup.-, NO.sup.+ BF.sub.4.sup.-, NO.sup.+ ClO.sub.4.sup.-, (CF.sub.3).sub.2 SO.sub.4, 2,4,6-trinitrophenol, 2,4,6-trinitrophenylsulfonic acid and 2,4,6-trinitrophenylcarboxylic acid, or is sodium, potassium, rubidium, cesium, calcium or barium or one of their amides, the latter being added, if appropriate, in tetrahydrofuran, dimethoxyglycol, anthracene, naphthalene or 2-methylstyrene. The conductive heteropolyphenylenes may be used in the electrical industry for the production of solar cells, for conversion and fixing of radiation and for the production of electric…
