Abstract

Polymer solutions are formed by reacting an aromatic heterocyclic such as thiophene, substituted thiophenes or oligomers of either with an acceptor doping agent (Lewis Acid) such as arsenic pentafluoride in the presence of certain solvents such as arsenic trifluoride. Articles such as air-stable conductive poly(3-methylthiophene) are cast from such solutions.
