Abstract Dibromides and diiodides with quinoxaline, phenylimidazole, and hexa-or pentaphenylarylene fragments were synthesized from dihalotolans obtained from chloral. Oligoarylene ethynylenes were synthesized by the reaction of the monomers with equimolar amounts of diethynyl aromatic compounds in the presence of the Pd II complex. Oligomers with imidazole and hexa (penta) arylbenzene cycles are soluble in amide organic solvents ...
