摘要:
The novel complex of the formula I ##STR1## can be produced for example by electrochemical oxidation of 2-fluoro-5,6,11,12-tetraselenotetracene in the presence of an inert organic solvent and a bromide-containing electrolyte. The novel 2-fluoro-5,6,11,12-tetraselenotetracene can for its part be produced by reacting 2,3-naphthalenedicarboxylic anhydride, in the presence of a Friedel-Crafts catalyst, with fluorobenzene to 2-(4-fluorobenzoyl)-naphthalene-3-carboxylic acid; cyclizing this to 2-fluoro-5,12-naphthacenequinone; reducing the 2-fluoro-5,12-naphthacenequinone to 2-fluorotetracene; reacting the 2-fluorotetracene with sulfuryl chloride to 2-fluoro-5,11- or 2-fluoro-6,12-dichlorotetracene; and finally reacting the last-mentioned at elevated temperature with selenium to obtain 2-fluoro-5,6,11,12-tetraselenotetracene. The complex of the formula I is metallically conducting, and is distinguished by a stable metallic phase down to at least 5.degree. K. It can be used for example as an organic conductor element.

摘要:
As a result of the action of electron acceptors, for example chlorine, bromine and/or iodine, on compositions containing a linear, branched or structurally crosslinked polymer and an unsubstituted or substituted tetrathionaphthalene, tetraselenonaphthalene, tetratelluronaphthalene, tetrathiotetracene, tetraselenotetracene or tetratellurotetracene, electrical conductivity is imparted to the compositions through the formation of charge-transfer complexes. These compositions are suitable for the production of mouldings, filaments, fibres, coatings and composite materials which have an antistatic finish or are electrically conducting.
