Synthesis of polymers containing polyaniline fragments linked by 1,4-benzoquinone groups

Abstract

Michael reaction of 1,4-benzoquinone and N-acetyl-4,4'-diaminodiphenylamine has afforded a new polymer; hydrolysis of the latter has yielded a product containing polyaniline fragments connected by 1,4- benzoquinone units in the backbone. The interaction of 1,4-benzoquinone and 1,4-phenylenediamine has afforded an earlier described polymer that has been characterized by IR and UV spectroscopy. 2,5-Bis[(4-aminophenyl)amino]-1,4-benzoquinone prepared from the mentioned compounds at a 3: 2 molar ratio under the same reaction conditions, can exist in three tautomeric forms. Electroconductivity of the prepared polymers increases from <10^–10 to 10^–6 S/cm with the doping level increase.
