Abstract
We have discovered a novel method of preparation of highly conductive polymers: the simultaneous solid state polymerization and doping of poly(p-phenylene) oligomers by the action of strong Lewis acids such as AsF5. We have previously shown that higher molecular weight poly(p-phenylene), PPP, can be doped with either strong electron acceptors (AsF5, IF5, HSO3F, SO3, SbCl5) or donors (Na, K, Li) to form highly conducting complexes.2,3 In the present case, we have observed that biphenyl, p-terphenyl, p-quaterphenyl, p-quinquephenyl and p-sexiphenyl polymerize and dope in the presence of AsF5 to form acceptor-doped metallic poly(p-phenylene). We have also observed that the donor dopant, potassium reacts with p-oligophenylenes to form highly conductive complexes, although in this case there is no evidence for increased chain length.
