Enhanced performance of triarylamine redox electrodes through directed electrochemical polymerization

Abstract

Molecular variations are incorporated in a triphenylamine-thiophene monomer to direct the polymerization and structure of electro-active polymer electrodes. When methyl groups are inserted at the 4-position of tris(4-(thiophen-2-yl)phenyl)amine, electropolymerization occurs solely at the 5-position resulting in a polymer electrode with enhanced Faradaic charge storage over an expanded potential range.
