| Abstract: | This article describes the synthesis of a novel series of soluble polyarylenes containing alternating binapthylene and biphenylene structural units. They were obtained by the cation-radical polymerization of bis(1-naphthyl) biphenyls. The following monomers were synthesized and polymerized : 4,4′-bis(1-naphthyl) biphenyl ( 9 ), 3,3′-bis(1-naphthyl) biphenyl ( 10 ), 2,2′-bis(1-naphthyl)biphenyl ( 11 ), and 2,5-bis(1-naphthyl)biphenyl ( 14 ). All polymerizations were performed in nitrobenzene using FeCl3 as oxidant. Polymers with number average molecular weights of up to 4000 g/mol were obtained. |
