Conjugated polymers were prepared by electroreduction of aryl dihalides in presence of nickel complexes as catalysts. For instance, poly(1,4-phenylene) was obtained from 4,4′-dibromobiphenyl in high yield (85%). According to the coupling mechanism

Homogeneous films of poly(1,4-phenylene) (PPP) can be deposited on various materials by electro-reduction of 4,4′-dibromobiphenyl in presence of a nickel complex catalyst. UV and IR spectra indicate that the polymer has a regular structure (exclusi

We present an optical study of polyparaphenylene samples polymerized by electoreduction of 4-4′ dibromo-biphenyl. By elemental analysis, a smaller amount of remaining bromine atoms is found with respect to PPP samples synthesized by the “Yamamoto
