Abstract

Abstract A novel polymer of triphenylamine, which may be a homopolymer of 4,4',4"-triphenylamine units, a copolymer of 4,4',4"-triphenylamine units and 1,4-benzene units or a homopolymer of 4,4'-(4"-unsubstituted or 4"-alkyl or alkoxyl) triphenylamine. This polymer is prepared by first carrying out Grignard reaction between a halogenotriphenylamine and metallic magnesium and then polymerizing the obtained Grignard reagent in a nonreactive organic solvent by using a nickel compound catalyst. This polymer acquires high conductivity by doping with an electron accepting dopant, and the conductivity is stable in the atmosphere. This polymer is useful as an electrode material in a device using a liquid electrolyte and is advantageous in being stable to repetition of electrochemical oxidation and reduction.
